Neutralinos and charginos in supersymmetric economical 3-3-1 model

Abstract

Fermion superpartners - neutralinos and charginos in the supersymmetric economical 3-3-1 model are studied. By imposition R parity, their masses and eigenstates are derived. Assuming that Bino-like is dark matter, its mass density is calculated. The cosmological dark matter density gives a bound on mass of LSP neutralino in the range of 20 - 100 GeV, while the bound on mass of the lightest slepton is in the range of 60 - 130 GeV
