B-physics trigger: bug-fix for the low mass Drell-Yan chains for Run 3 (ATR-19354)

Here we are trying to perform a fit of two muons from different collections, i.e. at least one muon should pass the isolation criteria. An additional filter for decisionIDs is introduced to avoid mixing of the isolated muons with EFCB muons from previous step.

Affected chains (+ with L1DY-BOX-2MU3V):

  • 'HLT_mu4_ivarloose_mu4_b7invmAB9vtx20_L12MU3V'
  • 'HLT_mu4_ivarloose_mu4_b11invmAB60vtx20_L12MU3V'
  • 'HLT_mu6_ivarloose_mu6_b11invmAB24vtx20_L12MU5VF'
  • 'HLT_mu6_ivarloose_mu6_b24invmAB60vtx20_L12MU5VF'
