| Popis: | We consider the minimum extension of the SM denominated 2HDM-III, in which,it new coupling constants to the new Higgs field in the Lagrangian of Yukawa are added furtheremore a Majorana mass in generated via See-Saw mechanism SSM-I thus, the effective masses of the Dirac and Majorana neutrinos will be sensitive to te VEV of Higgs doublets and to the structure of the Yukawa constants. Then we consider the MSS-III,in which a $Z_{2}$ symmetry is imposed to Lagrangian 2HDM-III to attach a doublet to the particles of the SM, and the other doublet to the triplet of fermions included in this mechanism. Finally, the MSS-I+III is simultaneously implemented in the M2DH-III. This is important because the additional heavy fermions in the adjoint representation of the weak isoespin group $SU(2)$ allows them to interact with the gauge bosons, facilitating their production in the colliding experiments.
