Muon information § In CMSSW_2_1_X, the information on various types of muons has been assembled in one single collection of Muon. Collection, “muons”. This collection serves as the main entry point for accessing muon-related information. § Available information in Ntuple • Basic kinematics • To which category a object belongs: § is. Global. Muon(), is. Stand. Alone. Muon(), is. Tracker. Muon() • Energy deposition in calorimeter • isolation parameters • Muon identification § Example: The muon id algorithm recommended by the muon POG is muon. is. Global. Muon() && muon. combined. Muon()->normalized. Chi 2()<10 § Impact parameter of track § number of hits in tracker

Muon isolation § § § Scalar sum of p. T of all tracks and the number of tracks in a cone of radius 0. 3/0. 5 around the muon trajectory: n. Tracks, sum. Pt, Scalar sum of ET in ECAL and HCAL in a cone of 0. 3/0. 5: em. Et, had. Et For tracker: • track. Iso = sum. Pt § § Example: track. Iso < 3 Ge. V in the cone of 0. 3 will give a 96. 7% efficiency for isolated muons from W or Z decays with about a factor of 10 rejection of muon candidates reconstructed in QCD events ( in qq. H, H -> ZZ/WW analysis, muons are all from W or Z) For calorimeters • calo. Iso = had. Et+em. Et § For further cut on the relative isolation • rel. Iso = (track. Iso+calo. Iso)/muon. Pt § The optimal isolation selection is specific to each particular analysis

Electron information § Read the standard offline electron Gsf. Electron. Collection, “pixel. Match. Gsf. Electrons” § Basic kinematics, track. Momentum. At. Calo, Track. Position. At. Vtx, etc § Electron identification • Reco. Egamma/Electron. Identification/src/Cut. Based. Electron. ID. cc in which one can choose robust, tight or loose selection for electron quality • The variables used for electron id here ( e. Super. Cluster. Over. P, track. Momentum. At. Vtx, track. Mumentum. Out, hadronic. Over. Em, delta. Phi. Super. Cluster. Track. At. Vtx, delta. Eta. Super. Cluster. Track. At. Vtx, etc ) also available in our Ntuple. So one can optimize the selection specific to qq. H analysis.

Jet information § Calo. Jet. Collection § Gen. Jet. Collection § different jet algorithm (iterative. Cone 5, …) can be chosen in configuration file § Jet plus track corrections are provided in two ways • create collection of JPT corrected jets: Jet. Plus. Track. ZSPCor. Jet. Icone 5 • correct jets “on the fly” using JPT correction service § Replace Calo response of tracks with tracks energy § Add energy of tracks in cone at Vtx but of cone at Calo § Subtract response of tracks out of cone at Vtx but in cone at Calo
