MC_QCD_PARTONS

Generic parton-level Monte Carlo validation analysis for <X> + jets.
Experiment: ()
Status: VALIDATED
Authors:
  • Frank Siegert
No references listed
Beams: * *
Beam energies: ANY
Run details:
  • Any <X> + jets.

Only partons (excluding top quarks) are taken into account to construct a kt cluster sequence. Thus this analysis can be used as a generic validation tool for QCD activity.
