Description

We build the complete supersymmetric version of a $SU(3)_{C}\otimes SU(2)_{L}\otimes U(1)_{Y^{\prime}}\otimes U(1)_{B-L}$, where $B$ and $L$ are the usual baryonic and leptonic numbers, gauge model ($SUSY321 Y^{\prime}(B-L)$) with total lepton number $L=+1$ using the superfield formalism. This model is interesting because generate masses for all neutrinos; there is good candidate to Dark Matter; there are flat directions; the lightest right-handed sneutrino, due a Majorana phases in its masses matrices, can induce Leptogenesis and also CP violation, in order to explain the matter asymmetry in the universe. We also, present an analysis of the mass spectrum of the fermions, gauge bosons and the scalar fields are presented.
