long time running without result

Processes 2->5 are too difficult for CalcHEP.
And you have too many of them.

Dear Alexander Pukhov

Thanks for your reply which clarifies the problem.
From your answer, are the processes with decay chains too difficult for CalcHEP ?
I couldn't find which step could add the decay informations in the Interactive mode,
is there a way to do that?

Thanks again,
Yuchen Guo

Thanks Alexander Belyaev, that solved my question.
