Zero weights in ~1/2 of sample
Asked by
Jiri Kvita
Dear experts,
I am trying to generate matched Z' and Z'+jets with MG5_aMC_v2_6_4 with the following commands
import model Abelian_
generate p p > zp > t t~, t > j j b, t~ > j j b~ @0
add process p p > zp > t t~ j, t > j j b, t~ > j j b~ @1
and at the Delphes (3.4.1) level I see ~1/2 of Event_weight are zero, rest are nonzero, in summery for the 10k test samle e.g.
4113 evts: w=0
5873 evts: w=4.03607e-08
Is this expected? Should I really ditch events with zero weights? I do not know how to trace the problem down to whether this is a mg5 or Delphes related question.
Cheers and many thanks,
Jiri Kvita
