Hi all,
I'm working in a very simplified model, and I want to couple the new particle content only to the first generation of quarks and leptons. Is there a way to do it properly during the implementation?

Thank you in advance,
Sebastian

The simplest way is to write a coupling to all generations and choose the numerical values of the couplings you don't want to have in the pheno study to be zero.

Hi Florian,
Thank you so much for your advice.

Best,
Sebastian
