Matrix amplitude

Asked by Kanhaiya Gupta

Can we calculate Matrix element (Amplitude of a process) rather than cross-section in MadGraph?

If yes, Can we please tell me how to do this?

Thanking you!

Olivier Mattelaer suggests this article as an answer to your question:
FAQ #2746: “Can I just calculate the amplitudes for a (sub)process and check them point-by-point in phase space points (in fortran/C++/Python)”.
