SoftDisplacedVertices

Framework for Soft Displaced Vertices analysis.

This package is currently in a preliminary stage. Tracks are selected and passed to the InclusiveVertexFinder to reconstruct secondary vertices.

The extension of standard MiniAOD and NanoAOD is done by applying the same set of conditions, calibrations, and alignments in the standard processing chain.
For instance our 2018 RunII MC reprocessing chain is based on the following:
SUS-chain_RunIISummer20UL18wmLHEGEN_flowRunIISummer20UL18SIM_flowRunIISummer20UL18DIGIPremix_flowRunIISummer20UL18HLT_flowRunIISummer20UL18RECO_flowRunIISummer20UL18MiniAODv2_flowRunIISummer20UL18NanoAODv9-00066.

We first generate a customised version of SUS-RunIISummer20UL18MiniAODv2-00068,
and then a customised version of SUS-RunIISummer20UL18NanoAODv9-00068.

For different MC files it might be worth checking:

• History of MC Production Campaigns
• NanoAOD Specific Explanations for the MC Campaigns

JME Uncertainty Calculations

To add the JME shifted variables to nanoAOD, do the following:

cd CMSSW_10_6_30/src
git clone git@github.com:alikaanguven/jetmet-uncertainties.git PhysicsTools/NanoAODTools
cd PhysicsTools/NanoAODTools
cmsenv
scram b

Then, follow the README of jetmet-uncertainties repository.
