Abstract

We analyse the neutral scalar sector of the MSSM without R-parity. Our analysis is performed for a one-generation model in terms of "basis-independent" parameters, and includes one-loop corrections due to large Yukawa couplings. We concentrate on the consequences of large Rp violating masses in the soft sector, which mix the higgses with the sleptons, because these are only constrained by their one-loop contributions to neutrino masses. We focus on the effect of Rp -violation on the Higgs mass and branching ratios. We find that the experimental lower bound on the lightest CP-even Higgs in this model can be lower than in the MSSM.
