Adapt track-vertex association in PUPPI (v15) [11_1_X] #31494

ahinzmann · 2020-09-17T13:10:00Z

PR description:

The purpose of this backport is to enable study of PUPPI tune v15 in the context of the HLT-TDR. The default configuration is not touched here, but may only be changed after successful validation of PUPPI v15 for Phase-2.
This introduces the option to use a new treatment of the track-vertex association for charged particles in PUPPI. The new version is called v15.
The vertex association is adapted to deal with split vertices in high hadronic activity events (more on this here: https://indico.cern.ch/event/944339/contributions/3968152/attachments/2086414/3505127/splitverticesandhighptjets.pdf).
Charged particles associated to one of the leading two pileup vertices by the vertex fit (fromPV=0), but found within dz<0.2 of the primary vertex are treated as coming from the primary vertex.
This reduces MET tails due to particles that are wrongly associated to a PU vertex, when the PV is reconstructed as 2-3 split vertices.
The overall impact on jet response, jet efficiency, fake rate, boosted object tagging is negligible.
Thus JEC and SFs derived with PUPPI v14 are applicable to PUPPI v15.
A summary of the studies is in:

for #31494 b4d614f

the update is consistent with a backport of Adapt track-vertex association in PUPPI (v15) #31174 (the original v15) and Sync puppi tune for phase2 with run3 #31887 (the phase-2 update for it); changes are made in the confines of the no-change policy
jenkins tests pass and comparisons with the baseline show no differences

However,
please note that in 11_1_X the no-change policy is relaxed: changes are allowed for phase2.
If the code is needed for HLT TDR related studies, it may be practical to put the relevant phase2.toModify updates in CommonTools/PileupAlgos/python/Puppi_cff.py instead of CommonTools/PileupAlgos/python/customizePuppiTune_cff.py
IIRC, the pre-phase2 setup was not explicitly granted free changes/updates.
So, the customizePuppiTune_cff will likely have to stay for Run3 or earlier Run2 studies/samples.

This pull request is fully signed and it will be integrated in one of the next CMSSW_11_1_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_11_2_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)
