Change model

Asked by Andrea

I'd like to simulate the process proton-proton in tau-tau-higgs. I have to add at the lagrangian of the Standard Model the effective operator \frac{1}{\Lambda^2}(\bar l_L\sigma_\mu_\nu \tau_R)HF^\mu^\nu. How I can do it? Or rather, how do I change the default model for emulation?

To change the model you can do
import model XXXXX

The full list of supported model can be displayed via
display modellist
but it is typically easier to go to the FeynRules website to see the list generated by that tools and being publicly available.

With that tool, you can input your Lagrangian and FeynRules will generated a UFO model that can be used in MG5aMC (and many other tools in HEP)

Cheers,

Olivier
