Update Dark Photon muon lines: add displaced line

Merged Update Dark Photon muon lines: add displaced line
acasaisv/update-dp-muon into master
Merged Adrian Casais Vidal requested to merge acasaisv/update-dp-muon into master

Add displaced line with tight muonIDNN cut. The PT cut is set to 0, this is very important to maximize the sensitivity on the displaced dark photon search. Also add the option to veto shared hits on the dimuon mass line, disabled by default. Rate comparison with respect to already deployed DisplacedLine on MB

Hlt1DiMuonDisplaced:           91/ 10000, (  273.00 +/-    28.49) kHz
Hlt1DiMuonDisplacedSoftPT:     15/ 10000, (   45.00 +/-    11.61) kHz

Rate comparison with respect to already deployed DisplacedLine on KS2MuMu MC

Hlt1DiMuonDisplaced:          147/ 10000, (  441.00 +/-    36.10) kHz
Hlt1DiMuonDisplacedSoftPT:    298/ 10000, (  894.00 +/-    51.01) kHz

Goes with: lhcb-datapkg/ParamFiles!128 (merged)

Overhaul of PID: !1908 (merged)

There's probably going to be overlap with these other MR.

For the bandwidth division

  • Either state that any new lines are fixed, or fill in this table:
Line name Tuning parameter(s) Simulation sample
DiMuonNoIP MuonNN /eos/lhcb/user/a/acasaisv/mdf-bwdivision/39112230 (etamumugamma)
DiMuonNoIPNorm MuonNN (same cut as displaced) This line should have the same muonID cut as DimuonDisplacedSoftPT
