Reco/trigger configuration for SMOG 2023 injections

Saverio Mariani requested to merge samarian_SMOG_2023_PV_loose_reco into master

Following on update of the running conditions and physics objectives for 2023, this MR make some changes to the SMOG reco/trigger strategy:

  • Due to the gas flowing outside the cell (SMOG2 -> SMOG), the PV reconstruction windows (and the prefilters in selections) are loosened, following what also done in !1230 (merged). While the default is still PV reconstruction within the SMOG2 cell (to keep running on sim samples), the velo_open flag is used to bind a la SMOG PV reconstruction (see plots below).
  • Due to the loss in IP resolution because of the VELO opening, dimuon states, whose selection relies less on IP/IPchi2 cuts, are favoured in the strategy .
    • Additional SingleMuon and KsToPiPi lines are implemented
    • Monitoring of the mass and SVz for events selected by SMOG2DiMuonHighMass are added (tested and output histograms are there)
    • Monitoring of the mass and SVz for events selected by SMOG2KsToPiPi are added (tested and output histograms are there)
  • Also, the MR adds sequences for pp+SMOG2 with forward_then_matching tracking strategy
  • Finally, prescales for SMOG lines are set by rescaling the rates observed into the 06/23 VdM scan to a physics filling scheme/ODIN configuration (full details in this document)

Some more detailed information for the PVs:

  • plots for PV reconstruction performance with looser windows:
    • Reconstructed PVz, from July tomography data with default (red) or looser (blue) PV reco: PVz_tomography. As expected, more PVs in ~[-800, -541] and [-341, -300] are now reconstructed
    • Absolute reconstruction efficiency as a function of z, for simulated standalone pAr collisions with a la SMOG Ar injection PVz_efficiency
    • PVz resolution as a function of z, for simulated standalone pAr collisions with a la SMOG Ar injection PVz_resolution
