IFIC meeting

This document outlines the objectives and methodologies applied in analyzing neutrino data using Monte Carlo production techniques. Key focuses include familiarizing with run-by-run Monte Carlo production, studying correlations between the number of hits (Nhits) and beta values, and implementing pseudo-experiment generation. Notably, modifications to reconstruction code were made to incorporate beta information, and comprehensive statistics were collected from varied neutrino runs. The findings aim to improve understanding of neutrino behaviors and inform related experiments.

  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

  19. 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?
