An update on hit-based displaced vertex trigger (ATR-19322)

Kunihiro Nagano requested to merge nagano/athena:hitdv_latest_work135 into master
  • FastTrackFinder (FTF)
    • Send seeds to hypo
    • Cuts on track (for hit-based DV only)
      • A bug fix on pT calculation
      • Add second innermost hit
    • Change on the algorithm to judge whether SPs are used by track (from pointer to identifier)
    • A range to send SPs to hypo changed from 0.6 to 1.0
  • Hypo
    • Change on HLT jet pT threshold for seeding from 30 to 50 GeV
    • Search only around the regions where is near to some FTF seed, remove cases where sensible variables cannot be calculated due to out of seed
    • Fill monitoring histograms only for HLT jet seeding

With these changes, background rates are expected to be reduced.
