L1 seed: pPuppiTauTkMuon42_18

• pPuppiTauTkMuon42_18 : select one muon (GMTTkMuons) with $p_T>18$ GeV and one Tau (CL2Taus) with $p_T>42$ GeV - Table

HLT filters:

• hltL3fL1TkSingleMu18Filtered20:
  select one (minN = cms.uint32(1)) muon (hltPhase2L3Muons) with $p_T>20$ GeV, $|\eta|<2.1$ and at least 1 hit in the muon stations (minMuonStations = cms.int32(1))

• hltL3crIsoL1TkSingleMu22EcalIso0p41:
  select the muons with isolation in ECAL (varTag = cms.InputTag("hltPhase2L3MuonsEcalIsodR0p3dRVeto0p000")) less than 0.41 (same threshold in EB and EE)

• hltL3crIsoL1TkSingleMu22HcalIso0p40:
  select the muons with isolation in HCAL (varTag = cms.InputTag("hltPhase2L3MuonsHcalIsodR0p3dRVeto0p000")) less than 0.40 (same threshold in HB and HE)

• hltL3crIsoL1TkSingleMu22HgcalIso4p70:
  select the muons with isolation in HGCAL (hltPhase2L3MuonsHgcalLCIsodR0p2dRVetoEM0p00dRVetoHad0p02minEEM0p00minEHad0p00) less than 4.7

• hltL3crIsoL1TkSingleMu22TrkIsoRegionalNewFiltered0p07EcalHcalHgcalTrk:
  not clear

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

• 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.

• hltHpsSelectedPFTauLooseTauWPDeepTau:
  cut = cms.string('pt > 27 && abs(eta) < 2.1'), discriminator = cms.InputTag("hltHpsPFTauDeepTauProducer","VSjet"), workingPoints = cms.vstring('double t1 = 0.5419, t2 = 0.4837, t3 = 0.050, x1 = 27, x2 = 100, x3 = 300; if (pt <= x1) return t1; if (pt >= x3) return t3; if (pt < x2) return (t2 - t1) / (x2 - x1) * (pt - x1) + t1; return (t3 - t2) / (x3 - x2) * (pt - x2) + t2;')

$p_T$ value	DeepTauVSjet Loose WP
$p_T\leq27$ GeV	0.5419
$27<p_T<100$ GeV	0.5419 + (0.4837 - 0.5419) / (100 - 27) * ($p_T$ - 27)
$100p_T<300$ GeV	0.4837 + (0.050 - 0.4837) / (300 - 100) * ($p_T$ - 100)
$p_T\geq300$ GeV	0.050

• NOTE: Why is the Medium WP at a lower level than the Loose WP for $p_T$ around 100 GeV ?

• hltHpsPFTau27LooseTauWPDeepTau:
  select single HPS Tau (hltHpsSelectedPFTauLooseTauWPDeepTau) with $p_T>27$ 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.
