Abstract

We release FeynRules and UFO model files for the $\nu$SMEFT -- the effective field theory of the Standard Model extended with right-handed neutrinos, $N_R$. These model files include dimension-five and dimension-six Higgs-$N_R$ operators. They are made publicly available on https://github.com/arsenii-titov/vSMEFT.git .
