Abstract

We study the radiative corrections to the mass of the lightest Higgs boson of the MSSM from three generations of Majorana neutrinos and sneutrinos. The spectrum of the MSSM is augmented by three right handed neutrinos and their supersymmetric partners. A seesaw mechanism of type I is used to generate the physical neutrino masses andoscillations that we require to be in agreement with present neutrino data. We present a full one-loop computation of these Higgs masscorrections and analyze in full detail their numerical size in terms of both the MSSM and the new sneutrino parameters. A criticaldiscussion on the different possible renormalization schemes and their implications, in particular concerning decoupling, is included.
