New usermod v2

Asked by Beojan

I'm trying to modify loop_sm to make the Higgs self-coupling and top Yukawa coupling modifiable at runtime.

The files in loop_sm say they were produced by FeynRules, so I'm trying to use usrmod v2 (https://cp3.irmp.ucl.ac.be/projects/madgraph/wiki/FAQ-NewPhysics-1#no1) but I'm getting errors due to a missing particles.dat. Is there a newer version of usrmod somewhere?

Alternatively, am I going about this is entirely the wrong way?

For NLO model, you have to pass by FeynRules/NLOCT for ANY modifications.

Cheers,

Olivier
