compute_widths results in KeyError : 'BSM'

Asked by Abhaya Kumar Swain

Hi MG5 team,

I am trying to compute decay width of a particle in a SUSY model. Before calculating the partial decay width of a particle I use the following command,

compute_widths h2

where h2 is a new particle. This results into the following error:
Command "compute_widths h2" interrupted with error:
KeyError : 'BSM'

I would appreciate any help in solving this error.

Thanks in advance
Abhaya

Hi,

This sounds an issue in your model.
I bet that you have some coupling tag as "BSM" in your model
but that the BSM flag is not defined anywhere in coupling_order.py

Cheers,

Olivier

PS: If this is not the case, then I would need more information (like the debug file, the name of the model,...)
If you need to attach file, please create a bug report (attachement are not allowed for question)

Can you help with this problem?
