k-factor in madgraph

Asked by diaspar1

MadGraph team hello,

Is there a parameter which works as a k-factor and changes cross-sections by a multiplication factor?
(i.e. if I put say 1.3 then the cross sections will be factorized by that number)

Thanks in advance,
Aviad

No,

but it is trivial to modify the lhe events to change the cross-section and the weight of each events.

Cheers,

Olivier
