Constructor & Destructor Documentation

◆ Pythia6PartonSelector()

Pythia6PartonSelector::Pythia6PartonSelector ( )

This is a Pythia6-specific parton selector that selects all status==2 partons. An explanation of the particle status codes returned by Pythia6 can be found in Section 5.4 of Pythia6 manual (http://arxiv.org/abs/hep-ph/0603175)
