How to incorporate three generations in model files?

Asked by Basabendu

Dear CalcHEP team,

I am calculating the relic density for a model (BSM) using micromega in which I have some of the exotic particles which have three generations (families). How do I incorporate this information in the CalcHEP model files?

Thank you

You have to implement each family member as an independent particle.
If all of them have the same mass, them micrOMEGAs will treat one of
them as a Dark Matter, assuming that other ones decay on it. Also it is
assumed that these decays are fast enough comparing with time of DM
formation.
