Detailed Description

Herwig++ parton selector derived from the base parton selector.

Definition at line 11 of file HerwigppPartonSelector.h.

Constructor & Destructor Documentation

HerwigppPartonSelector::HerwigppPartonSelector

(

)

This is a Herwig++-specific parton selector that selects all status==2 partons. This is likely a temporary choice since Herwig++ status codes in CMSSW currently break the HepMC convention. Once the status codes are fixed, the selector will be updated.
