In the context of the Standard Model (SM), the neutrinos are massless at any order in perturbation theory. However, today the experimental data show us neutrinos are massive and they oscillate. Therefore the generation of neutrino masses is an important issue in any realistic extension of the SM. One possible way to generate masses for the neutrinos are using the scheme of Gelmini-Roncadelli. In this scheme we introduce an extra triplet scalar, ∆, carries the lepton number of 2. In this scheme neutrinos get masses and they are Majorana particles, instead of Dirac particles and the double beta decay without neutrinos emission can occur. When we study the scalar spectrum of this model, in the CP odd sector, we get two Goldstone bosons. This extra Goldstone boson is known as Majoron. The Majoron is excluded experimentally. We can give large mass for Majoron with tiny vev of ∆. This mechanism is easily introduced in the supersymmetric version of this scheme. In this seminar we will present this model and also get its mass spectrum.
