IFIC meeting

1. IFIC meeting 11/Jan/2012 Agustín Sánchez Losa

2. Objectives @ NIKHEF • Get familiar with a Monte Carlo production (run by run) • Search/studycorrelations of Nhits and Beta • Get familiar withthepseudoexperimentsproductionwithAart’sreconstruction • ModifyAart’spseudoexperimentsproduction and reconstructioncodestoaddthe beta info • Checktheimprovement

3. 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

16. 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)

17. Distributions of log10(angleµ-ν) for different cuts in β (not normalized) 0.0<β<0.1 1.4<β<1.5

18. Distributions of log10(angleµ-ν) for different cuts in β (normaliced) 0.0<β<0.1 1.4<β<1.5

19. Evolution of the median in the different log10(angleµ-ν) distributions for different cuts in β 0.0<β<0.1 1.4<β<1.5

20. Programing • Add beta vsNhits histograms to: • Simulation • Likelihood

21. Nsig

22. Q

23. 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?
