Abstract: The μνSSM is a simple supersymmetric extension of the Standard Model (SM) capable of predicting neutrino physics in agreement with experiment. In this talk I discuss interesting phenomena related to the radiative corrections to the neutral scalar masses. In particular, I emphasize the importance of considering also the corrections suppressed by factors of the neutrino Yukawa couplings, as such terms can be enhanced by the inverse of the tiny vacuum expectation values of the left-handed sneutrinos. I show that at the one-loop level sizable contributions from the stop-sector enter in the sneutrino sector, yielding a striking correlation between the SM Higgs-boson mass and the left-handed sneutrino masses induced by their dependence on the soft breaking-parameter Atop.
