Detailed Description

Helper class for defining the generated Monte Carlo physics process.

The bits decode if certain particle types are present in the final state of the hard sub-process. Additionally, in events with a Higgs bosons, its decay is denoted, e.g. ProcessFlag::has( PF::higssbb ) is true for an event with a H->bbbar decay. See enum PF for individual flag bits.
