Reduce PT and tighten corrChi2 of DiMuonHighMass

Carla Marin Benito requested to merge cmarinbe_dimuonhighmasstune into 2024-patches

Follows a request from B&Q to reduce the muon PT cut of HLT1DiMuonHighMass. To keep the rate under control, the corrChi2 cut is tightened. The exact changes are:

  • muon pt = 1400 MeV -> 700 MeV
  • maxCorrChi2 = 5 -> 1.8

This changes the rate of the line from around 15 to 17 kHz on nominal expected-2024 MC. Thanks to @tevans for the numbers!

The same changes are applied to all the tuned configurations. The muon PT cut was never tighter than 1400 MeV, so the rate of the lines was never smaller than 15 kHz. The new configuration gives 17 kHz, so it should be fine for all the tunings.

Todo:

  • wait for PPG approval

FYI @tevans @cagapopo
