HLT_DoubleMediumChargedIsoPFTauHPS40_eta2p1

7.HLT_DoubleMediumChargedIsoPFTauHPS40_eta2p1

L1 seed: pDoublePuppiTau52_52

• pDoublePuppiTau52_52 : select two Taus (CL2Taus) with $p_T>52$ GeV - Table

HLT filters:

• hltPreDoublePFTauHPS:
  prescaler with offset = cms.uint32(0)

  • NOTE: Offset is set to 0.

• hltHpsSelectedPFTausTrackFinding:
  cut = cms.string('pt > 0'), discriminator = cms.InputTag("hltHpsPFTauTrackFindingDiscriminator"), selectionCut = cms.double(0.5), src = cms.InputTag("hltHpsPFTauProducer")

Looks for a track matching the Tau within $\Delta R = 0.5$

• hltHpsPFTauTrack:
  select single HPS Tau (hltHpsPFTauProducer) with no $p_T$ cut, with $|\eta|<2.5$ and triggerType=84.

  • NOTE: The minimum eta value is correct: when it is negative, the condition is not applied.

  • NOTE: Are we selecting only one tau? The path indicates two taus.

• hltHpsSelectedPFTausTrackPt1MediumChargedIsolation:
  cut = cms.string('pt > 0'), discriminator = cms.InputTag("hltHpsPFTauMediumAbsOrRelChargedIsolationDiscriminator"), selectionCut = cms.double(0.5), src = cms.InputTag("hltHpsPFTauProducer")

Looks for Tau with 0.5 relative isolation

• hltHpsDoublePFTau40TrackPt1MediumChargedIsolation:
  select two HPS Taus (hltHpsSelectedPFTausTrackPt1MediumChargedIsolation) with $p_T>40$ GeV, with $|\eta|<2.1$ and triggerType=84

  • NOTE: The maximum eta value goes from 2.5 to 2.1, since the tau reconstruction in Phase 1 is based on tracking information. This should be changed for Phase 2 to extend the taus up to the HGCAL coverage.
