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 R-p 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 R-p-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. |
