Yes it should.

One think that you can try is to test this version of MG5aMC:
https://github.com/mg5amcnlo/mg5amcnlo/tree/3.5.0_twgt
mg5amcnlo/mg5amcnlo at 3.5.0_twgt
github.com

It was increasing number of events generated in case where unweighting efficiency was very low (which is likely your case)

Cheers,

Olivier

The number of produced events is 3335 instead of requested 10000. The following parameter values in run_card are different compared with the default ones:
