select the mediator of a process

Asked by Matt on 2018-09-07

Dear MG staff,

I'd like to compute the cross section of the process p p > e+ e- j j mediated by two heavy Majorana neutrinos (that have non-negligible interferences for their similar masses), but only selecting those processes that contain at least one of the two heavy neutrinos.

Is this possible in MG5?

Thanks in advance,
Matteo

It is certainly possible, even if in worse case scenario, you have to write a code doing the diagram filtering.

But it might be possible in a simpler way with syntax like
> p p > M1 | M2 > e+ e- j j

Cheers,

Olivier
