Rivet analyses

title: MC_QCD_PARTONS

Generic parton-level Monte Carlo validation analysis for + jets.

Experiment: ()

Status: VALIDATED

Authors: - Frank Siegert

References: none listed

Beams: * *

Beam energies: ANY

Run details: - Any + 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.
