Abstract

We review some of the main features of Bilinear R-Parity Violation (BRpV), defined by a quadratic term in the superpotential which mixes lepton and Higgs superfields and is proportional to a mass parameter epsilon. We show how large values of epsilon can induce a small neutrino mass without fine-tunning. We mention the effect on the mass of the lightest Higgs boson. Finally we report on the effect of BRpV on gauge and Yukawa unification, showing that bottom-tau unification can be achieved at any value of tan(beta).
