E/gamma pixel matching windows

• ePhi1: searching window in phi for the first hit in the electron hypothesis
• pPhi1: searching window in phi for the first hit in the positron hypothesis
• Phi2: searching window for the second hit (after the first hit the charge of the candidate seed is assigned )
• r2 F: searching window for the second hit in the endcap
• z2 B: searching window for the second hit in the barrel

Three sets of matching windows are used: Normal, Startup, and Large. The values of the window variables in each are:

Normal window

Startup window (SW)

Large window (LW)

L1 seeds

Jet and MET seeds

Muon seeds

The L1 muon-quality for:

• Single muon triggers require quality codes: 4 or 5 or 6 or 7
• Double muon triggers require: 3 or 5 or 6 or 7
• Triple or quadruple muon triggers require: 2, 3, 4, 5, 6, 7
• Muons in cross-channel triggers require the same quality codes as in single, double, triple or quadruple muon triggers, except for muons in cross-channel triggers of the type "SingleMu_* AND (other than muons trigger objects)" which requires the same quality codes as in double muon triggers.

Where the quality codes mean:

• 0 : Empty muon
• 1 : Halo muon
• 2 : Very Low Quality Type 1
• 3 : Very Low Quality Type 2
• 4 : Very Low Quality Type 3
• 5 : RPC unconfirmed candidate
• 6 : DT or CSC unconfirmed candidate
• 7 : DT/RPC or CSC/RPC Matched candidate

For more information about muon quality please see L1 muon quality.

Electron/Photon seeds

Tau seeds

In OpenHLT from CMSSW 21X and in regular HLT from 30X the L1 seeds to L2 are L1 Tau & L1 Central Jets!

Mixed-object seeds
