Displaced Photons HLT trigger on 2017 13 TeV data (CMS DP-2020/0xx)

The search for long-lived neutral particles decaying to single and double photons that arrive late in time uses dedicated displaced photon trigger. Details can be found in the DPS note.


eff_vs_photon_pt.png Efficiency vs Photon pT
Efficiency of the photon pT sequence of the signal trigger versus photon pT for data (black) and representative signal models, GMSB SPS8: Λ = 100 TeV; cτ = 10 cm and 1000 cm (blue and red respectively). The offline cut, placed at 70 GeV gives a 100% trigger efficiency.

eff_vs_HT.png Efficiency vs HT
Efficiency as a function of the event HT (scalar trasverse energy sum of the deposits in the hadronic calorimeter from jets with pT above 15 GeV in abs(eta)< 3) of the signal trigger for data (black) and representative signal models, GMSB SPS8: Λ = 100 TeV; cτ = 10 cm and 1000 cm (blue and red respectively). The offline cut, placed at 400 GeV gives a 100% trigger efficiency.

eff_vs_photon_time_cutting_on_photonID Efficiency vs Photon Seed Time 1
Efficiency of the standard photon identification sequence of the signal trigger versus photon seed time for data (black) and representative signal models, GMSB SPS8: Λ = 100 TeV; cτ = 10 cm and 1000 cm (blue and red respectively).

eff_vs_photon_time_cutting_on_displacedID Efficiency vs Photon Seed Time 2
Efficiency of the displaced photon identification sequence of the signal trigger versus photon seed time for data (black) and representative signal models, GMSB SPS8: Λ = 100 TeV; cτ = 10 cm and 1000 cm (blue and red respectively). For a typical run, this requirement reduces the rate of the trigger by ~20% for a mean PU= ~55 and inst lumi of ~1.5E34 cm-2s-1
