SU(2)U(1)

Asked by Mohammad

Hi,
Im trying to work with Feynrules to create models and then to implement them into madgraph.
Im trying to work with just the SU(2)U(1) group of the standard model without the SU(3).
The problem is that when I try to generate a simple QED process with mad graph using this SU(2)U(1) model, I have the following error when I try to launch :

Command "generate_events run_01" interrupted with error:
IndexError : list index out of range
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
More information is found in '/Users/altakach/Documents/Mad/MG5_aMC_v2_6_0/bin/tsetest/run_01_tag_1_debug.log'.
Please attach this file to your report.

Do Madgraph necessits an SU(3) color group in order to work?

Thank you in advance,
Best regards,
Mohammad

Hi,

We certainly have a lot of constraint related to QCD since it is handle in a quite specific way (due to the running and the link to the PDF).
I'm not sure what are the exact requirement, but I guess that you need to have 'aS' and 'G' coupling defined in your UFO model.
After that you can have a model without any mention of the SU(3) group.

Now without the debug file, I do not know which specific problem you faced (and if this is even related to the SU(3) group)

Cheers,

olivier

Hi,

Thank you for your fat response!
I already tried to add aS and G in my UFO model. However I still get the same error!

Then please copy-past the content of your debug file (or upgrade this ticket to a bug report such that you can attach the debug file).

Cheers,

Hi,

The problem is that the code does not handle correctly the run_card entry:
   = pdgs_for_merging_cut ! PDGs for two cuts above
I'm going to create a patch, but the easiest solution is to set this parameter to 0

Cheers,

Olivier
