CalcHEP

How to exclude some particles in the batch file?

Asked by Basabendu

Dear Experts,

I am running calchep in batch mode to obtain 3-body decay widths via Y--> 3*x. Now, I would like to remove some of the particles from the final state as well as from the propagators. How do I do that?

Thank you for the help.

I think you can write

               Process:   Y->X,X,X

and then

             Composite: X= ....

I do not know how to  restrict virtual particles  for batch.

But you can use par_scan instead of batch.

Here the user creates  code for numerical calculations results/n_calchep
and then calls from results/  directiory

../../bin/par_scan < task

where 'task'   is a text file the first line of which contains name of
variables and next lines contain  parameters .

Best
