66 Object reconstruction and identification The criteria for the overlap removal and the order that they are applied are shown in Table 3.3. They are defined mainly to minimise the overall object misidentification rate, hence priority is generally given to candidates with higher purity. Table 3.3.: The overlap removal criteria listed in the order in which they are applied. Reject Against Criteria Electron Electron Shared ID track, the electron to be rejected has lower p T τ had - vis Electron ∆ R < 0 . 2 τ had - vis Non-CT muon ∆ R < 0 . 2 , the muon only needs to satisfy p T > 2 GeV τ had - vis CT Muon ∆ R < 0 . 2 CT Muon Electron Shared ID track Electron Muon Shared ID track Jet Electron ∆ R < 0 . 2 , the jet is not a b -jet Electron Jet ∆ R < 0 . 4 Jet Muon ∆ R < 0 . 2 or ghost-associated [90] , the jet is not a b -jet and has < 3 associated tracks Muon Jet ∆ R < 0 . 4 Jet τ had - vis ∆ R < 0 . 2
