Objectives @ NIKHEF

• Get familiar with a Monte Carlo production (run by run)

• Search/study correlations of Nhits and Beta• Get familiar with the pseudoexperiments

production with Aart’s reconstruction• Modify Aart’s pseudoexperiments production

and reconstruction codes to add the beta info• Check the improvement

Analyzed data

• Production: Run by Run• Default cuts applied: (if not specified)

– If β and estimated angle errors were available– min Λ: -7.0– min β: 0.05– min β: 1.0

• Statistics:– All runs available from 44000 to 44999– Around 223 runs (223 files for µ and 441 for ν)– A total of 1.078.035 events analyzed:

• 861.458 out of 1.723.459 µ• 216.577 out of 316.366 ν

Analyzed data

• Production:– Run by Run– All neutrino runs available from 40000 to 49999

• Cuts in Λ:– min Λ = -5.4

• Cuts in β:– (0.0<β<0.1), (0.1<β<0.2), …, (1.4<β<1.5)

Distributions of log10(angleµ-ν) for different cuts in β (not normalized)

Programing

• Add beta vs Nhits histograms to:– Simulation– Likelihood

Nsig

Q

Road to CERN

• Check likelihood with beta and its improvement• Nothing new for flares (let’s see the workshop?

Damine didn’t answered yet)• For time calibration:– 2011 laser offsets– Plot of laser offsets evolution (like JPabol- muons’s

ones)– T0s with the new runsetups– Standards for muon and laser offsets?
