  1. HPS VLoose Tau Validation

  2. Datasets and Triggers • /HT/Run2012A-PromptReco-v1/RECO • HLT_IsoMu24_eta2p1_v* • JSON ( ipb) • Cert_190456-194479_8TeV_PromptReco_ Collisions12_JSON.txt (1.5 fb-1) • 0.7 fb-1 in 2012A, 0.8 fb-1 in 2012B • CMSSW_5_2_3_patch3

  4. Main Control Regions Z→μμControl Region Z→tμth Control Region • HLT_IsoMu24_eta2p1_v* • μ1: pT > 25 GeV, |η| < 2.1, Full μ ID (see next slide) • μ1 : 25 GeV<pT < 50 GeV • τ1: pT > 15 GeV, |η| < 2.3 • τ1: Full τ ID (see next slide) • ΔR(τ1,μ1) > 0.3 • Q(τ1)xQ(μ1) < 1 • mμτ < 80 GeV • mT(μ1,MET) < 40 GeV • cos(Δφ(μ1,τ1)) < -0.95 • pζ-0.875pζvis > -7 • b Jet veto if ΔR(b,μ1/τ1) > 0.3 • tight μ veto/MVA e veto for τ1 leg • μ2: pT > 15 GeV, |η| < 2.1 • μ2: μ ID without isolation • Q(μ1)xQ(μ2) < 1 • mμμ> 20GeV • b Jet veto if ΔR(b,μ1/μ2) > 0.3

  5. τ ID and μ ID • τ ID • HPS decay mode finding • HPS VLoose isolation with Δβ corrections within ΔR=0.5 • No PF charged hadrons with pT>1.5 GeV • No PF photons with pT>2.0 GeV • μ ID • Global muon • Good track fit χ2/N<10 • ≥1 chamber hit • ≥2 matching segments • impact parameter dxy<2mm • ≥1 pixel hit • ≥6 tracker layers with hits • μ isolation within ΔR=0.4 with Δβ corrections • Track isolation < 1 GeV • ECAL isolation < 1 GeV • not imposed for μ2!
