Is it possible to get an analytical expression for decay width?

Asked by Basabendu

Dear CalcHEP team,

I need the analytical expression for the decay width of a four-body process. Now, with calchep I can get mathematica/form/reduce output for the same. But when I am calling "sum_init.m" followed by "symb1.m" in mathematica, it is showing 'current summation is for 2-> 2 process only.' But the process I am generating is like: X -> A,B,C,D. Does it only consider 2->2 process then? I am using version 3.6.23.

Thank you.

One can use MATHEMATICA code menu line to present matrix element in Mathematica format.
