Some couplings have '1' order

Asked by Marco Merchand on 2019-09-25

Dear Madgrahp experts

I created a new BSM model with feynrules. I did all the sanity checks on it and it passed them all. After importing the model within magraph by calling

>import model I3HDM1 --modelname

I get the following error:

"InvalidModel : Some couplings have '1' order.
                     This is not allowed in MG.
                     Please defines an additional coupling to your model"

can you tell me how can I fix this issue?

Thanks

Marco

I was able to solve this problem. In the feynrules model file I just needed to include in one of the quartic couplings

InteractionOrder -> {NP, 1}

as mentioned in tutorial.

Thanks Marco
