Hi,
I was scrolling through your model (I don't have Mathematica on my mobile

) and have some remarks:
1)
chi0 appears only with one generation, i.e. there is nothing to mix
2)
The same for the scalars as far as I can see.
3)
is there any neutrino mass term in the model? I can't see one..
Cheers,
Florian

Yes, indeed I have included the mixing although physically speaking there is no mixing, since only one generation. However, the code seemed to complain when I did not include this "mixing".
Concerning the neutrino, no direct mass term, neutrino mass generation proceeds on one-loop level through coupling gX (fermion-scalar-neutrino).
Cheers,
Björn

As a far as I know, introducing "fictitious" mixings is usually a bad idea in SARAH. I tried to do it several times but finally realized that it leads to many problems. My guess is that that's precisely the origin of your issues. However, you mention that not including the mixing leads to problems as well... what sort of problems?
