QEE Hlt2 and Sprucing lines for ZMuMu without MuID
To facilitate background studies, adding in two Hlt2
lines (and two passthrough-Spruceing lines) investigating Z->mumu
decays where one or both muons do not require IS_MUON
.
Minor affectations of the builder structure for the existing lines of:
Hlt2QEE_ZToMuMu
Hlt2QEE_DiMuonSameSign
SpruceQEE_ZToMuMu
SpruceQEE_DiMuonSameSign
New Lines are:
Hlt2QEE_ZToMuMu_SingleNoMuID
Hlt2QEE_ZToMuMu_DoubleNoMuID
SpruceQEE_ZToMuMu_SingleNoMuID
SpruceQEE_ZToMuMu_DoubleNoMuID
Efficiencies on 5k Z->mumu MC: (Denominator CanRecoChildren
, =Muons{eta in LHCb Acceptance + Charged Long tracks})
Line: Hlt2QEE_ZToMuMuDecision Efficiency: 0.885 +/- 0.012
Line: Hlt2QEE_ZToMuMu_DoubleNoMuIDDecision Efficiency: 0.959 +/- 0.008
Line: Hlt2QEE_ZToMuMu_SingleNoMuIDDecision Efficiency: 0.919 +/- 0.011
Rates on 25k hlt1-filtered MinBias:
Line: Hlt2QEE_ZToMuMuDecision Incl: 0.0 +/- 0.0 kHz, Excl: 0.0 +/- 0.0 kHz
Line: Hlt2QEE_ZToMuMu_DoubleNoMuIDDecision Incl: 0.0 +/- 0.0 kHz, Excl: 0.0 +/- 0.0 kHz
Line: Hlt2QEE_ZToMuMu_SingleNoMuIDDecision Incl: 0.0 +/- 0.0 kHz, Excl: 0.0 +/- 0.0 kHz
Sprucing Retention on 1k Z->mumu MC: (Should be passthrough currently, just checking)
Chain: Hlt2QEE_ZToMuMu -> SpruceQEE_ZToMuMu Events: 1000->260->260 Retention: 1.000
Chain: Hlt2QEE_ZToMuMu_SingleNoMuID -> SpruceQEE_ZToMuMu_SingleNoMuID Events: 1000->281->281 Retention: 1.000
Chain: Hlt2QEE_ZToMuMu_DoubleNoMuID -> SpruceQEE_ZToMuMu_DoubleNoMuID Events: 1000->304->304 Retention: 1.000

To verify retention is actually selecting exactly the same events instead of 'no selection' or some issue with how we are testing it, increased the muon_pt cut required on the sprucing lines from 3 GeV to 15 GeV and verified that the retention dropped, which it did as follows.
Chain: Hlt2QEE_ZToMuMu -> SpruceQEE_ZToMuMu Events: 1000->260->251 Retention: 0.965 Chain: Hlt2QEE_ZToMuMu_SingleNoMuID -> SpruceQEE_ZToMuMu_SingleNoMuID Events: 1000->281->268 Retention: 0.954 Chain: Hlt2QEE_ZToMuMu_DoubleNoMuID -> SpruceQEE_ZToMuMu_DoubleNoMuID Events: 1000->304->280 Retention: 0.924

Re: Rates, we expect not to be able to see the Z lines in even 50k of Hlt1-filtered MinBias (see: !1989 (comment 6324135)), however we can be confident that the builders are working as expected via the fact that the efficiency for the Z->mumu line matches that calculated previously (0.889 +/- 0.027 on a slightly different amount of data) (see: !1989 (comment 6324192))

Hi @dzuliani, as QEE's co-subconvener for Trigger, offline processing and jets, would you like to give this MR a quick once-over before I move to asking the WorkPackages with this? I have discussed the necessity for these lines with @rjhunter offline a few times, but he is on holiday and I don't see a need to postpone these.
I think the behaviour of these lines and the implementation are working as expected and quite simple.

Hi @mvesteri, here's the Z NoMuID lines we discussed, hopefully the description is clear enough, would you like to make any comments before I pass it onto the shifter?

Hi @frodrigu, I've run these new lines past my WG (QEE) and RTA WP3, could we get a ci-test?
