Effective lagrangian with Majorana

Asked by Yuchen Guo

Dear experts,

 I write a model which contained the majorana neutrino and 4-fermion interactions by using FeynRules.
It could generate the UFO output files successfully. However, some error occured when I run the model in the MG5,
 "InvaliModel : Majorana can not be dealt in 4/6/... fermion interactions".
How to use the MG5 with the model which contain the four-fermion lagrangian with Majorana?
Is there any way to solve this problem?

Regards,

Yuchen Guo

Hi,

It is likely that we can not handle such model. If you want to test, you can comment that error in the code.
If you get result then you can trust those. If another error occurs then it means that we can not handle that process.

Cheers,

Olivier
