Extra Muon Bs2JpsiPhi Detached line B2CC

A Bs2JpsiPhi detached line with an extra non-signal muon of pT> 500 MeV in the event. Has to be merged after !1070 (merged)

To do:

  • Is junction an optimal dummy particle? : went for system, whcih is a diquark state according to PDGid, but it shouldn't matter because the parameters are as following:
|        Name       |     PdgID    |   Q  |      Mass     |   (c*)Tau/Gamma |  MaxWidth  |        EvtGen        |  PythiaID  |     Antiparticle     |
| system            |           90 |   0  |         0 eV  |           0 ns  |      0     |        system        |     90     |        self-cc       |
  • Do testing on MC and minbias

Efficiency:

Eff=|( 9.162357 +- 0.155938)%|

Rate:

Line:    Hlt2B2CC_BsToJpsiPhi_ExtraMuonLineDecision                              Incl:  0.20022692384702662 +/- 0.11 kHz, Excl:  0.0 +/- 0.0  kHz
  • Think where is it more appropriate to put the X2muBs builder

Note for the future: When FT OSMuon is fine-tuned for Run 3: fine-tune cuts on the extra muon (now loosely fine-tuned to the developing stage of OSMuon according to this version.

Based on studies by @alsidley, idea by @graven.
