ufo sm model that are ready to use form factor?

Asked by toodles

Dear sir,

I would like to modify the SM coupling with form factors. Folloring the instruction here, https://cp3.irmp.ucl.ac.be/projects/madgraph/wiki/FormFactors. I checked the init.py and
found that the default sm ufo model of MG5_aMC_v2_3_3 is not ready to use form factor.

My question is how to write a new sm with feynrules to allow using form factor?

Thank you very much!

Best Regards,
YY

Just run FR (the latest version) on the SM model, and you should get such model.

Cheers,

Olivier
