B-physics trigger: tighten up selection of D0/D(*)-/D_s-/Lambda_c- objects for bBmux chains (ATR-24275)

Vladimir Lyubushkin requested to merge lyubushk/athena:master-bBmux into master
  • Add cut for fabs(z0_trk - z0_muon)<10mm, where z0_trk(muon) is z0 impact parameter of the track(muon) wrt BeamSpot. This will reduce the combinatorial background significantly.
  • add cut for the transverse momentum of the D0/D(*)-/D_s-/Lambda_c- object (final values to be turned by analysis group)

Nevertheless the reduction is expected to be ~50-60%. So that, I mark bBmux chains as End-of-Fill.
