No events produced with MG5_aMC_v3_0_3

Asked by mohamed meziani kada

hello
I try to generate the process p p > h z [QCD, QED]using the loop_qcd_qed_sm_ Gmu model. It delivers me only the cross sections but no events.
Could you tell me why there is no events?
thank you

Hi,

You should have the details in 1804.10017.

But in short at NLO computing cross-section and generated plots is a challenge on it's own
and having the possibility to generate (unweighted) events without double counting with the parton-shower is another.
(and this is the crucial point obviously to have events that are meaningful for experimentalist/pheno)
Only the first is currently possible for electroweak correction.
Cheers,

Olivier
