1 Introduction
The119861119888meson is the ground pseudoscalarmeson of the 119887119888 sys-
tem [1] Compared with the heavy unflavored charmonium119888119888 and bottomonium 119887119887 the 119861
119888meson is unique in some
respects (1)Heavy quarkonia could be created in the parton-parton process 119894119895 rarr 119876119876 at the order of 1205722
119904(where 119894119895 = 119892119892
or 119902119902 119876 = 119887 119888) while the production probability for the119861119888meson is at least at the order of 1205724

where the gluon-gluon fusion mechanism is dominant atTevatron and LHC [2] The 119861
119888meson is difficult to produce
experimentally but it was observed for the first time via thesemileptonic decaymode119861
119888rarr 119869120595ℓ] in119901119901 collisions by the
CDF collaboration in 1998 [3 4] which showed the realisticpossibility of experimental study of the 119861
119888meson One of
the best measurements on the mass and lifetime of the 119861119888
meson is reported recently by the LHCb collaboration119898119861119888

= 5134plusmn110plusmn57 fs [6]With the running of the LHC the 119861
119888meson has a promising
prospect It is estimated that one could expect some 1010 119861119888
events at the high-luminosity LHC experiments per year [78] The studies on the 119861
119888meson have entered a new precision
era (2) For charmonium and bottomonium the strong andelectromagnetic interactions are mainly responsible for anni-hilation of the 119876119876 quark pair into final states The 119861
119888meson
carrying nonzero flavor number 119861 = 119862 = plusmn1 and lying below
the 119861119863 meson pair threshold can decay only via the weakinteraction which offers an ideal sample to investigate theweak decay mechanism of heavy flavors that is inaccessibleto both charmonium and bottomonium The 119861
119888weak decay
provides great opportunities to investigate the perturbativeand nonperturbative QCD final state interactions and soforth
With respect to the heavy-light 119861119906119889119904
mesons the doublyheavy 119861
119888meson has rich decay channels because of its
relatively large mass and that both 119887 and 119888 quarks can decayindividually The decay processes of the 119861
119888meson can be
divided into the following three classes [2 9ndash11] (1) the 119888quark decays with the 119887 quark as a spectator (2) the 119887 quarkdecays with the 119888 quark as a spectator (3) the 119887 and 119888 quarksannihilate into a virtual 119882 boson with the ratios of sim7020 and 10 respectively [2] Up to now the experimentalevidences of pure annihilation decay mode [class (3)] are stillnothing The 119887 rarr 119888 transition belonging to the class (2)offers a well-constructed experimental structure of charmo-nium at the Tevatron and LHC Although the detection ofthe 119888 quark decay is very challenging to experimentalists theclear signal of the 119861

group using the 119861119904rarr 119863

(where 119875 and 119881 denote the 119878119880(3) ground pseudoscalar andvectormesons resp) such as [17 34ndash37]with the BSWmodel[38 39] or IGSWmodel [40] [18 19 41] based on the Bethe-Salpeter (BS) equation [20ndash24 42] with potential models[25] with constituent quark model [26ndash28] with QCD sumrules [43] with the quark diagram scheme [29 30] with theperturbativeQCD approach (pQCD) [44ndash49] and so onTheprevious predictions on the branching ratios for the 119861
119888rarr
119861119875 119861119881 decays are collected in Table 3 The discrepancies ofprevious investigations arise mainly from the different modelassumptions Recently several phenomenological methodshave been fully developed to cope with the hadronic matrixelements and successfully applied to the nonleptonic 119861 decaysuch as the pQCD approach [44ndash49] based on the 119896
119879
factorization scheme the soft-collinear effective theory [50ndash57] and the QCD-improved factorization (QCDF) approach[58ndash63] based on the collinear approximation and powercountering rules in the heavy quark limits In this paper wewill study the119861
119888rarr 119861119875 119861119881 decays with the QCDF approach
to provide a ready reference to the existing and upcomingexperiments
This paper is organized as follows In Section 2 we willpresent the theoretical framework and the amplitudes forthe 119861
119888rarr 119861119875 119861119881 decays within the QCDF framework
Section 3 is devoted to numerical results and discussionFinally Section 4 is our summation

from scales lower than 120583 Since the hadronic matrix elementsinvolve long distance contributions one is forced to useeither nonperturbative methods such as lattice calculationsand QCD sum rules or phenomenological models relyingon some assumptions Consequently it is very unfortunatethat hadronic matrix elements cannot be reliably calculatedat present and that the most intricate part and the dominanttheoretical uncertainties in the decay amplitudes reside in thehadronic matrix elements
22 Hadronic Matrix Elements Phenomenologically basedon the power counting rules in the heavy quark limit Benekeet al proposed that the hadronic matrix elements could bewritten as the convolution integrals of hard scattering kernelsand the light cone distribution amplitudes with the QCDFmaster formula [58ndash63] The QCDF approach is widelyapplied to nonleptonic 119861 decays and it works well [66ndash76]

which encourage us to apply the QCDF approach to thestudy of 119861
119888rarr 119861119875 119861119881 decays Since the spectator is the
heavy 119887 quark who is almost always on shell the virtuality ofthe gluon linked with the spectator should be sim O(Λ2QCD)The dominant behavior of the 119861
119888rarr 119861 transition form
factors and the contributions of hard spectator scatteringinteractions are governed by soft processes According to thebasic idea of the QCDF approach [69 70] the hard and softcontributions to the form factors entangle with each otherand cannot be identified reasonably so the physical formfactors are used as the inputs The hard spectator scatteringcontributions are power suppressed in the heavy quark limitFinally the hadronic matrix elements can be written as

The branching ratios of nonleptonic two-body 119861119888decays in
the rest frame of the 119861119888meson can be written as

where the lifetime of the 119861119888meson 120591
119861119888
= 5134 plusmn 110 plusmn 57 fs[6] and 119901 is the common momentum of final particles Thedecay amplitudesA(119861
119888rarr 119861119872) are listed in the Appendix
The input parameters in our calculation including theCKM Wolfenstein parameters decay constants and Gegen-bauer moments of distribution amplitudes in (8) are col-lected in Table 2 If not specified explicitly we will take theircentral values as the default inputs Our numerical results onthe 119862119875-averaged branching ratios are presented in Table 3where theoretical uncertainties of the ldquoQCDFrdquo column comefrom the CKM parameters the renormalization scale 120583 =(1 plusmn 02)119898
119888 decay constants and Gegenbauer moments
respectively For comparison previous results calculated withthe fixed coefficients 119886

There are some comments on the branching ratios(1) From the numbers in Table 3 it is seen that different
branching ratios for the 119861119888rarr 119861119875 119861119881 decays were obtained
with different approaches in previous works although thesame coefficients 119886
12are used Much of the discrepancy
comes from the different values of the transition formfactors If the same value of the form factor is used thenthe disparities on branching ratios for the 119886
1-dominated 119861
119888
decays will be highly alleviated For example all previouspredictions on B119903(119861
119888rarr 119861
119904120587) will be about 10 with the
same form factor119865119861119888rarr119861119904
0≃ 10 which is generally in linewith
the QCDF estimation within uncertainties and also agreeswith the recent LHCb measurement [12](2)There is a hierarchical structure between the QCDFrsquos
results on branching ratios for the 119861119888rarr 119861119875 and 119861119881 decays
with the same final 119861119902meson for example

which differs from the previous resultsThere are two decisivefactors One is the kinematic factor The phase space for the119861119888rarr 119861119881 decays is more compressed than that for the 119861
119888rarr
119861119875 decays because the mass of the light pseudoscalar meson(except for the exotic 1205781015840meson) is generally less than themassof the corresponding vector meson with the same valencequark components The other is the dynamical factor The

orbital angular momentum for the 119861119875 final states is ℓ119861119875= 0
while the orbital angular momentum is ℓ119861119881= 1 for the 119861119881
final states(3) According to the CKM factors and the coefficients
11988612 there is another hierarchy of amplitudes among the
QCDFrsquos branching ratios for the 119861119888decays which could
be subdivided into different cases (see Table 4) The CKM-favored 119886
1-dominated 119861
119888rarr 119861
119904120587 decays are expected to
have the largest branching ratio sim10 within the QCDFframework In addition the branching ratios for the Cabibbofavored 119861+

0 decays are also larger than 1which might be promisingly detected at experiments(4)There are many uncertainties on the QCDFrsquos results
The first uncertainty from the CKM factors is small due tothe high precision on Wolfenstein parameter 120582 with only03 relative errors [1] Large uncertainty comes from therenormalization scale especially for the 119886

119861119906119875 119861
119906119881 decays In principle the second uncertainty could
be reduced by the inclusion of higher order 120572119904corrections to
hadronic matrix elements It has been showed [77 78] thattree amplitudes incorporatingwith theNNLOcorrections arerelatively less sensitive to the choice of scale than the NLOamplitudes As aforementioned large uncertainty mainlycomes from hadron parameters such as the transition formfactors which is expected to be cancelled from the rate ofbranching ratios For example

Particularly the relation of (18) might be used to givesome information on the coefficients 119886
12and to provide an
interesting feasibility research on the validity of the QCDFapproach for the charm quark decay Finally we would like topoint out that many uncertainties from other factors such asthe final state interactions which deserve the dedicated studyare not considered here So one should not be too seriousabout the numbers inTable 3Despite this our resultswill still
provide some useful information to experimental physiciststhat is the Cabibbo favored119861

4 Summary
In prospects of the potential 119861119888meson at the LHCb experi-
ments accurate and thorough studies of the 119861119888decays will be
accessible very soonThe carefully theoretical study on the 119861119888
decays is urgently desiderated In this paper we concentratedon the nonfactorizable contributions to hadronic matrixelements within the QCDF framework while the transitionform factors are taken as nonperturbative inputs which isdifferent from previous studies It is found that the branchingratios for the Cabibbo favored 119861

119904120588 119861
119906119870 decays
are very large and could be measured earlier by the runningLHCb experiment in the forthcoming years

decay width from the 119888 quark decay [31ndash33] many theoreticalpapers were devoted to the study of the 119861
119888rarr 119861119875 119861119881 decays
(where 119875 and 119881 denote the 119878119880(3) ground pseudoscalar andvectormesons resp) such as [17 34ndash37]with the BSWmodel[38 39] or IGSWmodel [40] [18 19 41] based on the Bethe-Salpeter (BS) equation [20ndash24 42] with potential models[25] with constituent quark model [26ndash28] with QCD sumrules [43] with the quark diagram scheme [29 30] with theperturbativeQCD approach (pQCD) [44ndash49] and so onTheprevious predictions on the branching ratios for the 119861
119888rarr
119861119875 119861119881 decays are collected in Table 3 The discrepancies ofprevious investigations arise mainly from the different modelassumptions Recently several phenomenological methodshave been fully developed to cope with the hadronic matrixelements and successfully applied to the nonleptonic 119861 decaysuch as the pQCD approach [44ndash49] based on the 119896
119879
factorization scheme the soft-collinear effective theory [50ndash57] and the QCD-improved factorization (QCDF) approach[58ndash63] based on the collinear approximation and powercountering rules in the heavy quark limits In this paper wewill study the119861
119888rarr 119861119875 119861119881 decays with the QCDF approach
to provide a ready reference to the existing and upcomingexperiments
This paper is organized as follows In Section 2 we willpresent the theoretical framework and the amplitudes forthe 119861
119888rarr 119861119875 119861119881 decays within the QCDF framework
Section 3 is devoted to numerical results and discussionFinally Section 4 is our summation

scheme are listed in Table 1 The values of NLO Wilsoncoefficients in Table 1 are consistent with those given by [6465] where a trick with ldquoeffectiverdquo number of active flavors119891 =415 rather than formula (4) is used
To obtain the decay amplitudes the remaining work ishow to accurately evaluate the hadronic matrix elements⟨119861119872|119876
119894(120583)|119861
119888⟩ which summarize the physics contributions
from scales lower than 120583 Since the hadronic matrix elementsinvolve long distance contributions one is forced to useeither nonperturbative methods such as lattice calculationsand QCD sum rules or phenomenological models relyingon some assumptions Consequently it is very unfortunatethat hadronic matrix elements cannot be reliably calculatedat present and that the most intricate part and the dominanttheoretical uncertainties in the decay amplitudes reside in thehadronic matrix elements
22 Hadronic Matrix Elements Phenomenologically basedon the power counting rules in the heavy quark limit Benekeet al proposed that the hadronic matrix elements could bewritten as the convolution integrals of hard scattering kernelsand the light cone distribution amplitudes with the QCDFmaster formula [58ndash63] The QCDF approach is widelyapplied to nonleptonic 119861 decays and it works well [66ndash76]

which encourage us to apply the QCDF approach to thestudy of 119861
119888rarr 119861119875 119861119881 decays Since the spectator is the
heavy 119887 quark who is almost always on shell the virtuality ofthe gluon linked with the spectator should be sim O(Λ2QCD)The dominant behavior of the 119861
119888rarr 119861 transition form
factors and the contributions of hard spectator scatteringinteractions are governed by soft processes According to thebasic idea of the QCDF approach [69 70] the hard and softcontributions to the form factors entangle with each otherand cannot be identified reasonably so the physical formfactors are used as the inputs The hard spectator scatteringcontributions are power suppressed in the heavy quark limitFinally the hadronic matrix elements can be written as

The input parameters in our calculation including theCKM Wolfenstein parameters decay constants and Gegen-bauer moments of distribution amplitudes in (8) are col-lected in Table 2 If not specified explicitly we will take theircentral values as the default inputs Our numerical results onthe 119862119875-averaged branching ratios are presented in Table 3where theoretical uncertainties of the ldquoQCDFrdquo column comefrom the CKM parameters the renormalization scale 120583 =(1 plusmn 02)119898

There are some comments on the branching ratios(1) From the numbers in Table 3 it is seen that different
branching ratios for the 119861119888rarr 119861119875 119861119881 decays were obtained
with different approaches in previous works although thesame coefficients 119886
12are used Much of the discrepancy
comes from the different values of the transition formfactors If the same value of the form factor is used thenthe disparities on branching ratios for the 119886
1-dominated 119861
119888
decays will be highly alleviated For example all previouspredictions on B119903(119861
119888rarr 119861
119904120587) will be about 10 with the
same form factor119865119861119888rarr119861119904
0≃ 10 which is generally in linewith
the QCDF estimation within uncertainties and also agreeswith the recent LHCb measurement [12](2)There is a hierarchical structure between the QCDFrsquos
results on branching ratios for the 119861119888rarr 119861119875 and 119861119881 decays

which differs from the previous resultsThere are two decisivefactors One is the kinematic factor The phase space for the119861119888rarr 119861119881 decays is more compressed than that for the 119861
119888rarr
119861119875 decays because the mass of the light pseudoscalar meson(except for the exotic 1205781015840meson) is generally less than themassof the corresponding vector meson with the same valencequark components The other is the dynamical factor The

orbital angular momentum for the 119861119875 final states is ℓ119861119875= 0
while the orbital angular momentum is ℓ119861119881= 1 for the 119861119881
final states(3) According to the CKM factors and the coefficients
11988612 there is another hierarchy of amplitudes among the
QCDFrsquos branching ratios for the 119861119888decays which could
be subdivided into different cases (see Table 4) The CKM-favored 119886
1-dominated 119861
119888rarr 119861
119904120587 decays are expected to
have the largest branching ratio sim10 within the QCDFframework In addition the branching ratios for the Cabibbofavored 119861+

119906119870
0 decays are also larger than 1which might be promisingly detected at experiments(4)There are many uncertainties on the QCDFrsquos results
The first uncertainty from the CKM factors is small due tothe high precision on Wolfenstein parameter 120582 with only03 relative errors [1] Large uncertainty comes from therenormalization scale especially for the 119886

119888rarr
119861119906119875 119861
119906119881 decays In principle the second uncertainty could
be reduced by the inclusion of higher order 120572119904corrections to
hadronic matrix elements It has been showed [77 78] thattree amplitudes incorporatingwith theNNLOcorrections arerelatively less sensitive to the choice of scale than the NLOamplitudes As aforementioned large uncertainty mainlycomes from hadron parameters such as the transition formfactors which is expected to be cancelled from the rate ofbranching ratios For example

Particularly the relation of (18) might be used to givesome information on the coefficients 119886
12and to provide an
interesting feasibility research on the validity of the QCDFapproach for the charm quark decay Finally we would like topoint out that many uncertainties from other factors such asthe final state interactions which deserve the dedicated studyare not considered here So one should not be too seriousabout the numbers inTable 3Despite this our resultswill still
provide some useful information to experimental physiciststhat is the Cabibbo favored119861

4 Summary
In prospects of the potential 119861119888meson at the LHCb experi-
ments accurate and thorough studies of the 119861119888decays will be
accessible very soonThe carefully theoretical study on the 119861119888
decays is urgently desiderated In this paper we concentratedon the nonfactorizable contributions to hadronic matrixelements within the QCDF framework while the transitionform factors are taken as nonperturbative inputs which isdifferent from previous studies It is found that the branchingratios for the Cabibbo favored 119861

119904120588 119861
119906119870 decays
are very large and could be measured earlier by the runningLHCb experiment in the forthcoming years

which encourage us to apply the QCDF approach to thestudy of 119861
119888rarr 119861119875 119861119881 decays Since the spectator is the
heavy 119887 quark who is almost always on shell the virtuality ofthe gluon linked with the spectator should be sim O(Λ2QCD)The dominant behavior of the 119861
119888rarr 119861 transition form
factors and the contributions of hard spectator scatteringinteractions are governed by soft processes According to thebasic idea of the QCDF approach [69 70] the hard and softcontributions to the form factors entangle with each otherand cannot be identified reasonably so the physical formfactors are used as the inputs The hard spectator scatteringcontributions are power suppressed in the heavy quark limitFinally the hadronic matrix elements can be written as

The input parameters in our calculation including theCKM Wolfenstein parameters decay constants and Gegen-bauer moments of distribution amplitudes in (8) are col-lected in Table 2 If not specified explicitly we will take theircentral values as the default inputs Our numerical results onthe 119862119875-averaged branching ratios are presented in Table 3where theoretical uncertainties of the ldquoQCDFrdquo column comefrom the CKM parameters the renormalization scale 120583 =(1 plusmn 02)119898

There are some comments on the branching ratios(1) From the numbers in Table 3 it is seen that different
branching ratios for the 119861119888rarr 119861119875 119861119881 decays were obtained
with different approaches in previous works although thesame coefficients 119886
12are used Much of the discrepancy
comes from the different values of the transition formfactors If the same value of the form factor is used thenthe disparities on branching ratios for the 119886
1-dominated 119861
119888
decays will be highly alleviated For example all previouspredictions on B119903(119861
119888rarr 119861
119904120587) will be about 10 with the
same form factor119865119861119888rarr119861119904
0≃ 10 which is generally in linewith
the QCDF estimation within uncertainties and also agreeswith the recent LHCb measurement [12](2)There is a hierarchical structure between the QCDFrsquos

which differs from the previous resultsThere are two decisivefactors One is the kinematic factor The phase space for the119861119888rarr 119861119881 decays is more compressed than that for the 119861
119888rarr
119861119875 decays because the mass of the light pseudoscalar meson(except for the exotic 1205781015840meson) is generally less than themassof the corresponding vector meson with the same valencequark components The other is the dynamical factor The

orbital angular momentum for the 119861119875 final states is ℓ119861119875= 0
while the orbital angular momentum is ℓ119861119881= 1 for the 119861119881
final states(3) According to the CKM factors and the coefficients
11988612 there is another hierarchy of amplitudes among the
QCDFrsquos branching ratios for the 119861119888decays which could
be subdivided into different cases (see Table 4) The CKM-favored 119886
1-dominated 119861
119888rarr 119861
119904120587 decays are expected to
have the largest branching ratio sim10 within the QCDFframework In addition the branching ratios for the Cabibbofavored 119861+

119906119870
0 decays are also larger than 1which might be promisingly detected at experiments(4)There are many uncertainties on the QCDFrsquos results
The first uncertainty from the CKM factors is small due tothe high precision on Wolfenstein parameter 120582 with only03 relative errors [1] Large uncertainty comes from therenormalization scale especially for the 119886

119888rarr
119861119906119875 119861
119906119881 decays In principle the second uncertainty could
be reduced by the inclusion of higher order 120572119904corrections to
hadronic matrix elements It has been showed [77 78] thattree amplitudes incorporatingwith theNNLOcorrections arerelatively less sensitive to the choice of scale than the NLOamplitudes As aforementioned large uncertainty mainlycomes from hadron parameters such as the transition formfactors which is expected to be cancelled from the rate ofbranching ratios For example

Particularly the relation of (18) might be used to givesome information on the coefficients 119886
12and to provide an
interesting feasibility research on the validity of the QCDFapproach for the charm quark decay Finally we would like topoint out that many uncertainties from other factors such asthe final state interactions which deserve the dedicated studyare not considered here So one should not be too seriousabout the numbers inTable 3Despite this our resultswill still
provide some useful information to experimental physiciststhat is the Cabibbo favored119861

4 Summary
In prospects of the potential 119861119888meson at the LHCb experi-
ments accurate and thorough studies of the 119861119888decays will be
accessible very soonThe carefully theoretical study on the 119861119888
decays is urgently desiderated In this paper we concentratedon the nonfactorizable contributions to hadronic matrixelements within the QCDF framework while the transitionform factors are taken as nonperturbative inputs which isdifferent from previous studies It is found that the branchingratios for the Cabibbo favored 119861

119904120588 119861
119906119870 decays
are very large and could be measured earlier by the runningLHCb experiment in the forthcoming years

3 Numerical Results and Discussions
The branching ratios of nonleptonic two-body 119861119888decays in
the rest frame of the 119861119888meson can be written as

The input parameters in our calculation including theCKM Wolfenstein parameters decay constants and Gegen-bauer moments of distribution amplitudes in (8) are col-lected in Table 2 If not specified explicitly we will take theircentral values as the default inputs Our numerical results onthe 119862119875-averaged branching ratios are presented in Table 3where theoretical uncertainties of the ldquoQCDFrdquo column comefrom the CKM parameters the renormalization scale 120583 =(1 plusmn 02)119898

There are some comments on the branching ratios(1) From the numbers in Table 3 it is seen that different
branching ratios for the 119861119888rarr 119861119875 119861119881 decays were obtained
with different approaches in previous works although thesame coefficients 119886
12are used Much of the discrepancy
comes from the different values of the transition formfactors If the same value of the form factor is used thenthe disparities on branching ratios for the 119886
1-dominated 119861
119888
decays will be highly alleviated For example all previouspredictions on B119903(119861
119888rarr 119861
119904120587) will be about 10 with the
same form factor119865119861119888rarr119861119904
0≃ 10 which is generally in linewith
the QCDF estimation within uncertainties and also agreeswith the recent LHCb measurement [12](2)There is a hierarchical structure between the QCDFrsquos
results on branching ratios for the 119861119888rarr 119861119875 and 119861119881 decays
with the same final 119861119902meson for example

which differs from the previous resultsThere are two decisivefactors One is the kinematic factor The phase space for the119861119888rarr 119861119881 decays is more compressed than that for the 119861
119888rarr
119861119875 decays because the mass of the light pseudoscalar meson(except for the exotic 1205781015840meson) is generally less than themassof the corresponding vector meson with the same valencequark components The other is the dynamical factor The

0 decays are also larger than 1which might be promisingly detected at experiments(4)There are many uncertainties on the QCDFrsquos results
The first uncertainty from the CKM factors is small due tothe high precision on Wolfenstein parameter 120582 with only03 relative errors [1] Large uncertainty comes from therenormalization scale especially for the 119886

be reduced by the inclusion of higher order 120572119904corrections to
hadronic matrix elements It has been showed [77 78] thattree amplitudes incorporatingwith theNNLOcorrections arerelatively less sensitive to the choice of scale than the NLOamplitudes As aforementioned large uncertainty mainlycomes from hadron parameters such as the transition formfactors which is expected to be cancelled from the rate ofbranching ratios For example

Particularly the relation of (18) might be used to givesome information on the coefficients 119886
12and to provide an
interesting feasibility research on the validity of the QCDFapproach for the charm quark decay Finally we would like topoint out that many uncertainties from other factors such asthe final state interactions which deserve the dedicated studyare not considered here So one should not be too seriousabout the numbers inTable 3Despite this our resultswill still
provide some useful information to experimental physiciststhat is the Cabibbo favored119861

119906119870 decays have

4 Summary
In prospects of the potential 119861119888meson at the LHCb experi-
ments accurate and thorough studies of the 119861119888decays will be
accessible very soonThe carefully theoretical study on the 119861119888
decays is urgently desiderated In this paper we concentratedon the nonfactorizable contributions to hadronic matrixelements within the QCDF framework while the transitionform factors are taken as nonperturbative inputs which isdifferent from previous studies It is found that the branchingratios for the Cabibbo favored 119861

are very large and could be measured earlier by the runningLHCb experiment in the forthcoming years

orbital angular momentum for the 119861119875 final states is ℓ119861119875= 0
while the orbital angular momentum is ℓ119861119881= 1 for the 119861119881
final states(3) According to the CKM factors and the coefficients
11988612 there is another hierarchy of amplitudes among the
QCDFrsquos branching ratios for the 119861119888decays which could
be subdivided into different cases (see Table 4) The CKM-favored 119886
1-dominated 119861
119888rarr 119861
119904120587 decays are expected to
have the largest branching ratio sim10 within the QCDFframework In addition the branching ratios for the Cabibbofavored 119861+

119906119870
0 decays are also larger than 1which might be promisingly detected at experiments(4)There are many uncertainties on the QCDFrsquos results
The first uncertainty from the CKM factors is small due tothe high precision on Wolfenstein parameter 120582 with only03 relative errors [1] Large uncertainty comes from therenormalization scale especially for the 119886

119861119906119875 119861
119906119881 decays In principle the second uncertainty could
be reduced by the inclusion of higher order 120572119904corrections to
hadronic matrix elements It has been showed [77 78] thattree amplitudes incorporatingwith theNNLOcorrections arerelatively less sensitive to the choice of scale than the NLOamplitudes As aforementioned large uncertainty mainlycomes from hadron parameters such as the transition formfactors which is expected to be cancelled from the rate ofbranching ratios For example

Particularly the relation of (18) might be used to givesome information on the coefficients 119886
12and to provide an
interesting feasibility research on the validity of the QCDFapproach for the charm quark decay Finally we would like topoint out that many uncertainties from other factors such asthe final state interactions which deserve the dedicated studyare not considered here So one should not be too seriousabout the numbers inTable 3Despite this our resultswill still
provide some useful information to experimental physiciststhat is the Cabibbo favored119861

4 Summary
In prospects of the potential 119861119888meson at the LHCb experi-
ments accurate and thorough studies of the 119861119888decays will be
accessible very soonThe carefully theoretical study on the 119861119888
decays is urgently desiderated In this paper we concentratedon the nonfactorizable contributions to hadronic matrixelements within the QCDF framework while the transitionform factors are taken as nonperturbative inputs which isdifferent from previous studies It is found that the branchingratios for the Cabibbo favored 119861

119904120588 119861
119906119870 decays
are very large and could be measured earlier by the runningLHCb experiment in the forthcoming years

orbital angular momentum for the 119861119875 final states is ℓ119861119875= 0
while the orbital angular momentum is ℓ119861119881= 1 for the 119861119881
final states(3) According to the CKM factors and the coefficients
11988612 there is another hierarchy of amplitudes among the
QCDFrsquos branching ratios for the 119861119888decays which could
be subdivided into different cases (see Table 4) The CKM-favored 119886
1-dominated 119861
119888rarr 119861
119904120587 decays are expected to
have the largest branching ratio sim10 within the QCDFframework In addition the branching ratios for the Cabibbofavored 119861+

119906119870
0 decays are also larger than 1which might be promisingly detected at experiments(4)There are many uncertainties on the QCDFrsquos results
The first uncertainty from the CKM factors is small due tothe high precision on Wolfenstein parameter 120582 with only03 relative errors [1] Large uncertainty comes from therenormalization scale especially for the 119886

119888rarr
119861119906119875 119861
119906119881 decays In principle the second uncertainty could
be reduced by the inclusion of higher order 120572119904corrections to
hadronic matrix elements It has been showed [77 78] thattree amplitudes incorporatingwith theNNLOcorrections arerelatively less sensitive to the choice of scale than the NLOamplitudes As aforementioned large uncertainty mainlycomes from hadron parameters such as the transition formfactors which is expected to be cancelled from the rate ofbranching ratios For example

Particularly the relation of (18) might be used to givesome information on the coefficients 119886
12and to provide an
interesting feasibility research on the validity of the QCDFapproach for the charm quark decay Finally we would like topoint out that many uncertainties from other factors such asthe final state interactions which deserve the dedicated studyare not considered here So one should not be too seriousabout the numbers inTable 3Despite this our resultswill still
provide some useful information to experimental physiciststhat is the Cabibbo favored119861

119906119870 decays have
large branching ratios ≳ 1 which could be detected earlier
4 Summary
In prospects of the potential 119861119888meson at the LHCb experi-
ments accurate and thorough studies of the 119861119888decays will be
accessible very soonThe carefully theoretical study on the 119861119888
decays is urgently desiderated In this paper we concentratedon the nonfactorizable contributions to hadronic matrixelements within the QCDF framework while the transitionform factors are taken as nonperturbative inputs which isdifferent from previous studies It is found that the branchingratios for the Cabibbo favored 119861

119906119870 decays
are very large and could be measured earlier by the runningLHCb experiment in the forthcoming years

orbital angular momentum for the 119861119875 final states is ℓ119861119875= 0
while the orbital angular momentum is ℓ119861119881= 1 for the 119861119881
final states(3) According to the CKM factors and the coefficients
11988612 there is another hierarchy of amplitudes among the
QCDFrsquos branching ratios for the 119861119888decays which could
be subdivided into different cases (see Table 4) The CKM-favored 119886
1-dominated 119861
119888rarr 119861
119904120587 decays are expected to
have the largest branching ratio sim10 within the QCDFframework In addition the branching ratios for the Cabibbofavored 119861+

0 decays are also larger than 1which might be promisingly detected at experiments(4)There are many uncertainties on the QCDFrsquos results
The first uncertainty from the CKM factors is small due tothe high precision on Wolfenstein parameter 120582 with only03 relative errors [1] Large uncertainty comes from therenormalization scale especially for the 119886

119888rarr
119861119906119875 119861
119906119881 decays In principle the second uncertainty could
be reduced by the inclusion of higher order 120572119904corrections to
hadronic matrix elements It has been showed [77 78] thattree amplitudes incorporatingwith theNNLOcorrections arerelatively less sensitive to the choice of scale than the NLOamplitudes As aforementioned large uncertainty mainlycomes from hadron parameters such as the transition formfactors which is expected to be cancelled from the rate ofbranching ratios For example

Particularly the relation of (18) might be used to givesome information on the coefficients 119886
12and to provide an
interesting feasibility research on the validity of the QCDFapproach for the charm quark decay Finally we would like topoint out that many uncertainties from other factors such asthe final state interactions which deserve the dedicated studyare not considered here So one should not be too seriousabout the numbers inTable 3Despite this our resultswill still
provide some useful information to experimental physiciststhat is the Cabibbo favored119861

4 Summary
In prospects of the potential 119861119888meson at the LHCb experi-
ments accurate and thorough studies of the 119861119888decays will be
accessible very soonThe carefully theoretical study on the 119861119888
decays is urgently desiderated In this paper we concentratedon the nonfactorizable contributions to hadronic matrixelements within the QCDF framework while the transitionform factors are taken as nonperturbative inputs which isdifferent from previous studies It is found that the branchingratios for the Cabibbo favored 119861

119904120587 119861
119904120588 119861
119906119870 decays
are very large and could be measured earlier by the runningLHCb experiment in the forthcoming years
