The group

Stony Brook HEP has two component groups –

A. The Neutrino and Nucleon Decay group funded by DOE Chang Kee Jung (Prof), Clark McGrew (Assoc Prof), Peter Paul (Dist.

Prof emeritus), currently working on SuperKamiokande, T2K, and planning for future large underground H2O Cerenkov detector.

HE and NN groups are closely allied intellectually and share technical and administrative services, seminars etc., but are distinct in scientific personnel and experiments.

The NSF and DOE high energy collider groups are fully unified, working on both ATLAS and DØ with common tasks, analyses, student supervision etc.

B. High Energy Collider group with portions funded by NSF and DOE – the focus of this review

(Mike Marx is part of the HE group; now Associate Provost for Brookhaven Affairs and not currently working on High Energy experiments.

Staff

We have technical and administrative staff who serve the combined NN and Collider groups.

Jack Steffens – technician Jack is on a State line, reimbursed by grants at the xx% level. The source of grant funds is adjusted annually dependent on the projects he is working on. Most recently he has spent most of his time on T2K POD detectors

Kim Kwee Ng – computer professional. Kim is 100% on a State line; he has departmental duties, but spends about 75% of his time supporting our computing operation.

Joan Napolitano – Administrative assistant who manages personnel and grant activities for NN, Collider and X-ray groups

Jennifer Flynn – Administrative assistant part time; procurements, travel.

(Dean Schamberger (co-PI on NSF Collider grant) is on a State line, reimbursed by grant funds at the 65% level. He provides computing and software service to the Department as a whole.)

In 2006, we lost the services of our electronics engineer to budget restrictions.

ILC activities

We expect that the discoveries at the LHC will need further study with a lepton collider, in which the character of these discoveries can be more completely understood. Grannis has played several leadership roles in developing the ILC as the next step for particle physics beyond the LHC. Initial co-chair of Americas LC steering group ILCSC (international steering group) ITRP technology choice group (warm vs. cold) White papers on ILC physics capabilities ILC parameters specification committee Chair of GDE Director search IDAG detector advisory group to validate detectors for inclusion in 2012 TDR DOE OHEP program manager for ILC 2005 - 07

Wrote papers outlining a plan for ILC running in a physics-rich scenario and on how to disentangle Susy states in data.

Chakrabarti developed tau identification (, , l) tools enabling determination of polarization for the SiD letter of intent.

Interactions between DOE and NSF collider groups The two portions of the collider group work together very closely on DØ

and ATLAS – we share the mentoring of students and postdocs and often collaborate on the same hardware and physics projects.

Weekly video meetings of both ATLAS and DØ groups (SB/CERN and SB/FNAL). All DOE and NSF faculty, postdocs and students participate with a weekly in-depth talk by one person and brief status reports by all.

Recent examples of Stony Brook DOE/NSF collaboration:

DØ W mass measurement: DOE supported faculty, postdoc, student & NSF faculty, student.

DØ Higgs searches: DOE side did h()b Susy H/A and SM Z()H(bb) (with partial supervision by NSF side) and NSF side did H() W/Z(qq). People worked closely together.

DØ ZZ production; jet energy resolution improvement

ATLAS calorimeter HV system, commissioning, calibration.

Proposed 3 year program - DØ

DOE and Fermilab have stated their firm intent to run CDF/DØ through Sept. 2011. We expect that by the end of the run, 12 fb-1 of data will be delivered (10 fb-1 to analyses). We can foresee scenarios in which a run in FY12 would be desirable. We intend to continue our DØ involvement at approximately the current level through the end of the Tevatron running.

Schamberger is the leading expert on the DØ LAr calorimeter operation. He will continue to be responsible for solving new problems and keeping the calorimeter running efficiently and precisely calibrated.

We will focus on two high priority DØ physics topics, continuing past work:(a) The Tevatron W mass measurements are presently the least restrictive components in constraining the SM. With the full data set, we expect to reach MW=16 MeV per expt (12 MeV Tevatron avg, 10 MeV World avg). LHC will have difficulty matching this precision! When the Higgs is discovered, its mass – in conjunction with W mass, top mass and Z observables – can tell us whether it is SM or something else. This is one of the primary Tevatron legacy measurements.

Overview 17

(b) The SM Higgs is now ruled out for MH<114 GeV (LEP) and for 160-170 GeV (Tevatron). Precision EW measurements strongly favor the lower end of the allowed range between 114 and 160 GeV which is the most difficult for LHC to reach. With 10 fb-1, Tevatron can rule out MH < 200 GeV where it does not exist.

10 fb-1

We will continue our present search for low mass Higgs in the jj final state. With a new student replacing Strauss, we intend to pursue one of the other low mass searches (the choice to be made on where we can maximally impact the Higgs searches).

Proposed 3 year program - ATLAS

In ATLAS, our current hardware responsibilities for the LAr calorimeters and silicon pixel detector will govern our initial efforts. Through our past accomplishments, we are well positioned to bring these detectors into routine operation quickly and to obtain accurate calibrations and algorithms for EM energy scale, missing ET, and b-tagging algorithms.

These activities lead us naturally to high priority physics topics. The initial effort will be on measurement of SM processes to verify that the analysis chain is robust. We will first concentrate on two topics: (a) measurements of W/Z inclusively, and with jets, and (b) multi-lepton production. The former allow confrontation of data with MC event generators where the latter are currently flawed and improvement in understanding QCD. The latter opens a window for Susy gaugino searches using the trilepton channels.

Subsequently we will extend to measurements of W/Z + heavy flavor jets. These QCD processes are the main backgrounds to many rare processes (top, Higgs, Susy, strong coupling, extra dimensions …). These measurements lead naturally to dedicated searches for new phenomena involving final states with W/Z and heavy quarks.

Overview 19

We expect upgrades to ATLAS to begin in the next three year grant period. ATLAS has internally approved a new inner layer of silicon pixels to be inserted inside the existing pixel detectors prior to the main LHC and ATLAS upgrades. This addition will occur before the main SLHC and detector upgrades. We have agreed to contribute to this IBL project, bringing the experience we gained from the DØ Layer 0 detector inserted within the pre-existing silicon strip detectors, as well as our involvement in the initial ATLAS pixel detector operation. Our focus will be on chip and sensor stave testing and development of simulation tools to evaluate and compare a range of design alternatives. We are collaborating with LBNL and SLAC on this project.

Further in the future, we expect upgrades of the LHC to higher luminosity which will necessitate major upgrades to the tracking system, with replacement of inner silicon strips by pixels and the outer TRT with silicon strips. We have tested prototype strip sensors in Stony Brook, and will continue to play a role in developing the silicon strip upgrades.

Overview of proposed budget Senior scientist salaries: 2 months summer for academic faculty;

25% time for Grannis; 65% of full salary for Schamberger.

Postdocs: 5 (1 DØ, 4 ATLAS) up 1 from past due to adding new faculty

Students: 7 (2 DØ, 5 ATLAS) up 1 from past due to adding new faculty

Staff: portion of administrative staff & technician, prorated across groups

Domestic travel, foreign travel, M&S, maintenance agreements taken from average expenditure over past 5 years.

Equipment: 2 server computers for ATLAS, 1 for D0. Other equipment requested to enable ATLAS pixel chip and stave testing and development.

Assume 3% year COL increases in out-year salaries except for students (recently raised), for travel and M&S. COL increase in SWF, travel, M&S partially offset by front-end loading of Equipment purchases.

Fringe rates at established campus rates.

Overhead at 75% off campus/25% on campus rates.
