Matrix element for polarized beam

Asked by sudesh gupta on 2020-09-29

Hi

I need to calculate matrix element for a process with - 75% polarized beam means "polbeam1 =75.0 ". How can I do that using "standalone" command or is there any other way?

Thank you
sudesh

Hi,

We do not provide such feature for standalone output.
(The basic idea of standalone is to be as simple as possible to allow other code to build on them).
This being said it should be quite simple to get that information (at least if you use the python wrapper, fortran is always a bit more complex by nature obviously)

Cheers,

Olivier
