How to speed up MadGraph if I only want to see the total cross section?
Asked by
Qiji Xin
Hi all,
I am a newer to Madgraph and using it to calculate a 2 → 3 process with pure electroweak, no QCD.
What I wanna know now is just the total cross section per run.
Now for one run to see the total cross section at one beam energy, it usually takes 40 min.
I have also tried CompHEP, and it only takes a couple minutes.
I think the time difference may be because MadGraph calculates/
So, if I just want the total cross section, are there anything I can do to speed MadGraph up?
Thanks very much!
