摘要：

We study Yukawa coupling unification in the simplest extension of the Minimal Supersymmetric Standard Model (MSSM) which incorporates R-parity violation through a bilinear superpotential term. In contrast to what happens in the MSSM, we show that bottom-tau unification at the scale M-GUT where the gauge couplings approximately unify can be achieved for any value of tan beta by choosing appropriately the sneutrino vacuum expectation value. Moreover, we show that in contrast with the MSSM where large tan beta solutions exist, in our case for sufficiently large sneutrino VEV upsilon(3), large tan beta becomes incompatible with bottom-tau unification.
