cuts on initial state photon invariant mass

Asked by Mamutjan

Hi

I want to implement a center of mass energy or invariant mass cut on initial state photon.
The process is a a > w- w + > e- e+ ve ve~.
How can I implement the invariant mass cut M(aa)< 1000 on photon in MadGraph or is it only possible when I do the analysis in ROOT?
Thank you.

Best
Mamutjan

Hi,

They are a FAQ on cuts. my internet connection is too erratic for me (this week) to find the exact link on that one.
in short you have to implement your cut in SubProcesses/cuts.f

Cheers,

Olivier
