I want to cut some process

Asked by Zongyang LU

Dear Olivier
When I generate a process, I want to add a cut condition to the generated case to filter out some of the processes. For example, I want to cut the process of photons in the case of e+e ->a | z>mu+mu -. How should I achieve it? Because the intermediate particles are not in the shell, I cannot cut through the data of the intermediate particles.
Sincerely,
Lu

This FAQ should give you the full control on the selected diagram.

otherwise for your case, you can ask only for the Z
e+ e- > z > mu+ mu-

Cheers,

Olivier
