Extension of electron matching in nanoAOD (backport) #33347

PR description:

Backport of #32966

Electron matching to MC truth has some inefficiency due to FSR. This PR extends the matching to recover such cases, by adding the possibility that electrons can be matched to gendressed particles. This issue has been reported here:
https://indico.cern.ch/event/962278/contributions/4060711/attachments/2136665/3599026/electron_matching_nano_nov4.pdf

and further discussed here:

cms-nanoAOD#552

The electron matching is performed as follows:

Electrons are first matched to a collection of dressed electrons. This collection is identical to the GenDressedLepton collection that is stored in nanoAOD, but with a looser pt cut. If there's a match, the Electron_genPartFlav variable is set to 1 or 15, depending on the mother of the dressed lepton. Electron_genPartIdx is the index of the electron en GenPart that corresponds to the constituent of the matched dressed leptons with highest pt and abs(pdgId)==11.
For the electrons not matched in the previous step, the logic is the same as in the previous implementation: electrons are matched to GenPart and then Electron_genPartIdx and Electron_genPartFlav are assigned according to this match.

mariadalfonso · 2021-04-08T15:17:23Z

this backport is not a 1:1 as you have now CandMCMatchTableProducer.cc and CandMCMatchTableProducerNew.cc
Not sure this is the best way to do it.
did you try to add a "bool ExtendMatching" so that we can protect the changed for the v8 production ?

mariadalfonso · 2021-04-08T15:17:29Z

please test

indeed, i thought the safest way would be to duplicate the module for the time being... Adding a bool ExtendMatching should be possible, but I'd have to change some of the consumes to "mayConsumes". If you confirm this is the way to go, I can do it

yes, please try with this options (cloning files such as CandMCMatchTableProducerNew will be unmaintainable).
Also now the PR got in conflict electrons_cff.py

@mariadalfonso sorry it took so long, I missed your last message. Just one procedural question: I applied the code checks and that changes parts of the code I didn't mean to change. Is this correct for a backport?

this "electronMCTableNew" is not used anymore in any sequence.
we should add modification into electronMCTable and have a simple way to take or not the new settings.

 electronSequence = cms.Sequence(bitmapVIDForEle + bitmapVIDForEleHEEP + isoForEle + ptRatioRelForEle + seedGainEle + slimmedElectronsWithUserData + finalElectrons)
 electronTables = cms.Sequence (electronMVATTH + electronTable)
 electronMC = cms.Sequence(electronsMCMatchForTable + electronMCTable)
+electronMCnew = cms.Sequence(particleLevelForMatching + tautaggerForMatching + matchingElecPhoton + electronsMCMatchForTable + electronsMCMatchForTableAlt + electronMCTableNew)
+( run2_nanoAOD_106Xv1 & ~run2_nanoAOD_devel).toReplaceWith(electronMC, electronMCnew)


we should have the new sequence by default and then for the v8 ( run2_nanoAOD_106Xv1 & ~run2_nanoAOD_devel) we should run the old sequence.

can you confirm that runs on both
runTheMatrix -l 1325.81 ( #test ttbar 106Xv1 )
and runTheMatrix -l 1325.7 ( # test ttbar 94XMiniAODv2)

thanks for the clarification, i misunderstood the meaning of the modifiers. I've just pushed the proper setting, along with some fixes. I confirm the runTheMatrix workflows are running properly

This pull request is fully signed and it will be integrated in one of the next CMSSW_10_6_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_12_0_X is complete. This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo, @qliphy (and backports should be raised in the release meeting by the corresponding L2)
