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

TL;DR

This paper investigates the properties and masses of neutralinos and charginos within a supersymmetric 3-3-1 model, analyzing dark matter implications and deriving bounds on particle masses based on cosmological data.

Contribution

It provides the first detailed analysis of neutralino and chargino spectra in the supersymmetric economical 3-3-1 model with dark matter considerations.

Findings

Dark matter density constrains neutralino mass to 20-100 GeV.

Bound on lightest slepton mass is 60-130 GeV.

Neutralino and chargino eigenstates are explicitly derived.

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
