Higgs and gauge boson phenomenology of the 3-3-1 model with CKS mechanism

TL;DR

This paper analyzes a 3-3-1 extension of the Standard Model, focusing on phenomenological constraints from collider data, lepton flavor violation, and dark matter, and explores the properties of the $Z'$ gauge boson and sterile neutrinos.

Contribution

It provides a comprehensive phenomenological analysis of the inert 3-3-1 model with CKS mechanism, including constraints on new particles and potential signals for future experiments.

Findings

$Z'$ bosons heavier than 4 TeV are consistent with experimental constraints.

Sterile neutrino masses are constrained to be lighter than 1.12 TeV by $oldsymbol{ ext{μ→eγ}}$ decay.

The model can account for the observed dark matter relic density.

Abstract

We perform a comprehensive analysis of several phenomenological aspects of the renormalizable extension of the inert 3-3-1 model with sequentially loop-generated SM fermion mass hierarchy. Special attention is paid to the study of the constraints arising from the experimental data on the $\rho$ parameter, as well as those ones resulting from the charged lepton flavor violating process $\mu\to e\gamma$ and dark matter. We also study the single $Z'$ production via Drell-Yan mechanism at the LHC. We have found that $Z'$ gauge bosons heavier than about $4$ TeV comply with the experimental constraints on the oblique $\rho$ parameter as well as with the collider constraints. In addition, we have found that the constraint on the charged lepton flavor violating decay $\mu\rightarrow e\gamma$ sets the sterile neutrino masses to be lighter than about $1.12$ TeV. In addition the model allows charged lepton flavor violating processes within reach of the forthcoming experiments. The scalar potential and the gauge sector of the model are analyzed and discussed in detail. Our model successfully accommodates the observed Dark matter relic density.
