Generate large number of events with weights

Asked by Amin Aboubrahim on 2017-12-05

Hi Olivier,

My question is about generating weighted events but let me explain the purpose.
In generating SM backgrounds for a 100 TeV collider, getting the good statistics for 1000 fb^-1 requires a huge number of events to be generated. What is the method followed to get good enough statistics while avoiding to have to generate O(10^9-10^10) events?
 Is generating weighted events the solution and how is it done in MG5?

Thank you very much,
Amin
