Supersymmetric 3-3-1 model with right-handed neutrinos

Abstract

We consider the supersymmetric extension of the 3-3-1 model with right-handed neutrinos.We study the mass spectra in the scalar and pseudoscalar sectors, and for a given set of the input parameters, we find that the lightest scalar in the model has a mass of 130 GeVand the lightest pseudoscalar has mass of 5 GeV. However, this pseudoscalar decouples from the Z0 at high energy scales since it is almost a singlet under SU_2_L _ U_1_Y.
