Problem computing widths for vertices with form factors
Hi experts,
I am attempting to calculate branching ratios in model where I have introduced some form factors in the vertices. I manage to generate some events with the model with no problem, except when I do
compute_widths __ or set the width of the particle to Auto.
When I do this, I get the error
Command "generate_events run_01" interrupted in sub-command:
"set max_npoint_
NameError : name 'Fgg' is not defined
Please report this bug on https:/
More information is found in 'MG5_debug'.
Please attach this file to your report.
(Fgg is the name of one of my form factors)
Is there a known issue with calculating decays widths for models including form factors, and is there a way to work around it?
I'm using Madgraph5 VERSION 2.6.6 .
Thanks very much in advance,
Lara
