Detailed Description

JetSelector selects Jets from any jet branch (JCCA, JCCB,...) using standard cuts. It is based on the SelectUserObjects class.

Usage: Here's a list of all configuration parameters used by the selector, along with their standard values.

Required parameters:

• .From: Name of the branch the selected jets are written to.

Optional parameters:

• .Tree: OutputTreeName[default: name()]
• .To: Name of the branch jets are selected from (default: .From branch name)
• .JES: "UnCorrected", "JES" (default), "JESShiftedPlus", "JESShiftedMinus" (JESshifted by +1 or -1 sigma), "JESMU" (jes corrected by the muon presence in the jet), "JESMUShiftedPlus", "JESMUShiftedMinus" (JESMU shifted by +1 or -1 sigma).
• .nJets: minimal number of jets to be selected [default 1]
• .nJetsMax: maximal number of jets to be selected [default -1 (no selection)]
• .pT: pT cut applied to jets [deafult: 0.0].
• .eta: The jets have to have an |eta| smaller than this number [default: 10.0]
• .detEta: The jets have to have |detEta| smaller than this number [default: 10.0]
• .Sort: sort jets in pT [default: false]

• .RequireVertexConf: require that TrackVertexJetID matchs the jet to the 0th P.V. [default: false].
• .VertexBranch: the name of the PrimaryVertex branch to use If this flag set to false following cuts can be used
  • .minCPF: Only jets with at least that much CPF from the 0th P.V. are selected [default: -999].

• .UseStandardID: use or not standard jet ID group's cut [default "true"] The "standard cuts" means cut saved in the CAF tree by d0correct. The following parameters will be applied only if this flag set to "false".

• .UseSmearedJets: use smeared jets

• .UseStandardQualityCuts: The quality part of standard criteria set will be used [default: false] If this flag set to false following cuts can be applied
  • .EMFmin: Minimal EM fraction a jet must have [default: 0.05].
  • .EMFmax: Upper limit for a jets EM fraction [default: 0.95].
  • .CHFmin: Lower limit for a jets CH fraction [default: 0.0]
  • .CHFmax: Maximum CH fraction a jet can have [default: 0.4].

• .UseStandardEMJetsRemoval: Use standard removal of jets matched to the EM objects [default: false]

• .UseStandardL1Conf: use standard L1 conformation [default: false]. If this flag set to false following cuts can be used
  • .L1cut: Is L1 confirmation required? [default: true]
  • .L1BoundOffs: When checking for L1 eta coverage, this value is subtracted from the actual L1 coverage eta range. [default: 0.2]
  • .f90noL1: When doing L1 confirmation, this is the maximum f90 value allowed for any jet (f90: # of towers w/ 90% of pT). [default: 0.5]
  • .CHFnoL1: When doing L1 confirmation, this is the maximum CH eT fraction allowed for any jet. [default: 0.5] The following parameters are used to cut on the ratio (jet L1 energy)/(jet pT x (1 - jet CH eT fraction)) in the CC, ICd and EC:
  • .l1cutCC, .l1cutICD, .l1cutEC [default: 0.4 for each]

If no optional parameters are given, the jet ID group's cuts are applied. Here's an example config file that shows how to use this jet selector:

cafe.Run: JetSelector(myJets)

myJets.To: GoodJet myJets.From: JCCB myJets.Tree: Preselection myJets.EMFmin: 0.05 myJets.EMFmax: 0.95 myJets.CHFmin: 0.0 myJets.CHFmax: 0.4 myJets.eta: 2.5 myJets.L1cut: false

Jets with 0.05<EMF<0.95, 0.0<CHF<0.4 and |eta|<2.5 are stored in the branch "GoodJet" that is added to a tree called "Preselection".
