Neutral Higgs sector of the MSSM without R-p

We analyse the neutral scalar sector of the MSSM without R-parity. Our anal ysis is performed for a one-generation model in terms of "basis-independent " parameters, and includes one-loop corrections due to large Yukawa couplin gs. 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 on ly 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 thi s model can be lower than in the MSSM.
