Dear Florian,

I am trying to generate the process t1 > c n1 in madgraph, so I read I have to use(or create) a model in SARAH that include this decay, or the coupling of the second quark family to the Higgs in the MSSM scenario, using the MSSM.m and particles.m files found in the Models folder in SARAH, however Im not really sure how to do this or if this model already exist.

I would appreciate any help you could give me in this regard.

Thanks for your time,


Juan Pablo

Hi,

I'm not sure if I understand the question. In general, all couplings are by default assuming the most general CP and flavour structure.

In general, if you are not familiar with the basics of SARAH, it might be good to work through these references: 1503.04200, 1507.06349

Cheers,
Florian
