Yukawa Unification on the Bilinear R-Parity model

Abstract

We discuss gauge and Yukawa unification in the context of a supersymmetric model with bilinear R-parity violation. We show that this model allows $b-\tau$ Yukawa unification for any value of $\tan \beta$ while satisfying perturbativity of the couplings. We also find the $t-b-\tau$ Yukawa unification easier to achieve than in the MSSM, occurring in a wider high $\tan \beta$ region. Finaly, we also discuss the compatibility between the predicted and the measured values for ${\alpha }_s(M_Z)$
