Monte Carlo Truth Definition of Jet Flavour in CMSSW

Complete: 2

Goal of this page

This page describes the status of porting of BTagMCTools package from ORCA to CMSSW. In the process, I'd love to solve some long standing issues regarding particle MC definitions, as they are available in the reconstruction software.

MC jet definition

  • from reconstructed jets
  • from MC candidates

MC particle definition

CMSSW has many different MC particle definitions, either inherited from various sources or develped ad hoc, used throughtout the similation, reconstruction, and analyusis processes.


Reco Jets

MC candidates are matched to Reco jets based on
  • pseudoangular distance from reco jet axis
  • area of interest of the reco jets (eg., for kT jets)

MC Jets

MC candidates are the constituents of MC jets; needs matching between MC and Reco jets

MC Jet flavours

  • parton based
  • hadron based
  • leptonic decay chain
