R45 vs PU ArturApresyan California Institute of Technology SaeidPaktinat School of Particles and accelerators, IPM
Introduction • R45 = (T4 – T5)/(T4 + T5) • T4 and T5 are in GeV. • Results for bothchanneland RBX wise are reported. • Number of the verticesisused as the PU measure. • GoodPrimaryVertexFilter and HBHENoiseFilter are applied. process.HBHENoiseFilter.useTS4TS5 = cms.bool(False)
Data • Datasets: • SingleMu_Run2011A-May10ReReco-v1_RECO • SingleMu_Run2011A-PromptReco-v4_RECO • MinimumBias_Run2011B-PromptReco-v1_RECO • MinimumBias_Run2011A-PromptReco-v5_RECO • Json file 23 Sep • Cert_160404-176309_7TeV_PromptReco_Collisions11_JSON.txt
Number of Vertices Drop in nVtx is slower in MinimumBias than SingleMu
R45 vs energy The overall shape is not affected by the pile up
R45 vs energy Almost same result for SingleMu dataset
R45 in different bins of nVtx R45 shape is almost same in different bins of nVtx.
R45 in different bins of nVtx • SingleMu
Efficiency of Noise Filter • The variable useTS4TS5 is turned on/off. • The efficiency goes down by increasing the number of the Vertices. The plot will be updated with y-label. Points are fitted with a horizontal line
Efficiency of Noise Filter • Efficiency is almost constant for SingleMu. Points are fitted with a horizontal line
T4 and T5 are for every single channel. Not added for the whole RBX.
