hit-based DV hypo optimization to reduce rate (ATR-19322)

Kunihiro Nagano requested to merge nagano/athena:hitdv_latest_work62 into master
  • To reduce trigger rates of hit-based DV chains down to a level evaluated with R21 R&D study
  • Namely, cut definitions are changed as
    • Tight: jet eta<1.0, seeds=jets only (previous: jet eta<2.0)
    • Medium: jet eta<2.0, seeds=jets only (previous: seeds=jets + 'unseeded')
  • New primary triggers are (evaluted with all-had ttbar MC + extralation with EB repro)
    Chain MC counts (input->output) Expected rate
    HLT_xe80_tcpufit_unconvtrk200_hitdv_tight_L1XE50 3136 -> 22 7-8 Hz
    HLT_unconvtrk260_hitdv_tight_L1J100 4829 -> 26 21 Hz
  • New supporting chains are (evaluted with all-had ttbar MC + EB repro)
    Chain MC counts (input->output) Expected rate
    HLT_xe80_tcpufit_unconvtrk200_hitdv_medium_L1XE50 3136 -> 36 12-14 Hz
    HLT_unconvtrk260_hitdv_medium_L1J100 4829 -> 44 36 Hz
  • C.f. the previous versions chains were (evaluated with all-had ttbar MC + EB repro)
    Chain MC counts (input->output) Rate (EB)
    HLT_xe80_tcpufit_unconvtrk200_hitdv_medium_L1XE50 3136 -> 187 61 Hz
    HLT_unconvtrk200_hitdv_tight_L1XE50 3136 -> 179 66 Hz
    HLT_unconvtrk200_hitdv_medium_L1XE50 3136 -> 1047 352 Hz
    HLT_unconvtrk260_hitdv_medium_L1J100 4829 -> 44 36 Hz
    HLT_unconvtrk260_hitdv_tight_L1J100 4829 -> 450 300 Hz
