bool checkVetoResonanceDecays | ( | const Event & | process | ) |
Class specific.
Return true of the resonance decays are vetoed.
Count the number of times hook is called.
Loop over particles and determine equivalent types.
If no list of mothers is provided, then all particles in hard process and resonance decays are counted together
Check if criteria is satisfied. inclusive mode: at least as many decay products as requested exclusive mode: exactly as many decay products as requested (but additional particle types not appearing in the list of requested daughter id's are ignored)
Inclusive criteria not satisfied, veto event
Exclusive criteria not satisfied, veto event
All criteria satisfied, don't veto
