Reweight Events : generate events with higher pt of jets

Asked by user1905

Hi experts,
I am trying to generate di-boson production, p p > w- w+, w- > l- vl~, w+ > j j. In my analysis I required more statistics for the higher pt jet, i.e, the number of jets having say 200 GeV should be higher. Can we do something in madgraph that would allow us to maintain to overall shape of pt, yet could offer us more events with higher pt jets.

 Any suggestion, solution or comments are appreciated?

Sorry for the late answer,

They are no real magic here. If you want to generate more events at high energy, then you need to give up on having unweighted events and in a way allow to have less accuracy at low pt. But the bias generation (see the linked FAQ) might be what you are looking for.

Cheers,
