Supersymmetric reduced minimal 3-3-1 model

TL;DR

This paper develops a supersymmetric minimal 3-3-1 model with two Higgs triplets, analyzing its particle mass spectrum, loop corrections for fermion masses, and constraints from Z boson decay modes.

Contribution

It introduces a supersymmetric version of the minimal 3-3-1 model with a simplified Higgs sector and studies its phenomenological implications.

Findings

Charged gauge boson and Higgs boson masses are equal at tree level.

Fermion masses for electrons, muons, neutrinos, and certain quarks arise from loop corrections.

Constraints on the model parameter ratio w/w' are derived from Z boson decay data.

Abstract

We build an supersymmetric version of the minimal 3-3-1 model with just two Higgs triplets using the superfield formalism. We study the mass spectrum of all particles in concordance with the experimental bounds. At the tree level, the masses of charged gauge bosons are the same as those of charged Higgs bosons. We also show that the electron, muon and their neutrinos as well as down and strange quarks gain mass through the loop correction. The narrow constraint on the ratio t_w = \frac{w}{w^\prime} is given by studying the new invisible decay mode of the Z boson.
