Neutrinos masses in the Supersymmetric B-L model with three non-identical right-handed neutrinos and Some Supersymmetric $(B-L)$ Models.

WWe give a review about the Minimal Supersymmetric Standard Model with three right-handed neutrinos (MSSM3RHN) and some Supersymmetric $(B-L)$ models. We, first introduce the minimal set of fields to built those models in their superfields formalism. After it, we build the lagrangian of those model in the superspace formalism and also introduce the soft terms to break SUSY.
