  1. TRT Digitation StudyM.Levchenko PNPI TRT Days 31.10.2013 PNPI M.Levchenko

  2. Qualification Topic Understanding the response of the TRT electronics to Muons . Establish baseline distributions of measurable quantities needed to validate and tune TRT digitization at different <mu> values from low to high. Start with low luminosity isolated muons. Then proceed to muons at higher <mu>. PNPI M.Levchenko

  3. Current Tuning Round Used digitization tag TRT_Dig00-11-00 TRT_PAI00-00-38 Datasets data11_7TeV.periodD.physics_Muons.PhysCont.DESD_SGLMU.pro10_v01/ + data11_7TeV.periodM.physics_Muons.PhysCont.DESD_SGLMU.pro10_v01/ ----- data12_8TeV.periodB.physics_Muons.PhysCont.DESD_SGLMU.repro14_v01/ MC 250kevt mc11_7TeV.147771.Sherpa_CT10_Zmumu.merge.HITS.e1443_s1372_s1370/ mc12_8TeV.147771.Sherpa_CT10_Zmumu.merge.HITS.e1434_s1499_s1504/ PNPI M.Levchenko

  4. <mu> data11 and mc11 Period D <µ> = 6 Period M <µ> = 15 PNPI M.Levchenko

  5. <mu> data12 period B PNPI M.Levchenko

  6. Z → μ+ μ- event selection • Trigger :EF_mu18(2011D), EF_mu18_medium(2011M) • EF_mu24_tight (2012B) • Muon type: StacoMuonCollection • Cut list (for all years) • |ɳ| < 2.0 • pT > 20 GeV • ΔR > 0.3 • 75 < Mmm < 105 GeV PNPI M.Levchenko

  7. In what we are interested? • How behaves Straw Efficiency over the <µ> • How behaves hitResiduals over the <µ> • LE(will be studied in nearest future) • HTprobability (will be studied ) PNPI M.Levchenko

  19. Conclusions and plans • Created framework for easy and fast access to the TRT information in different <µ> periods • Data samples found and used for <µ>=6,35 • First tuning for LowTreshold parameters is done. • Plans • look for the LE and HT probability behavior • Maybe something else • Prepare documentation concerning TRT Digitization Tuning PNPI M.Levchenko
