TL;DR

This paper explores the properties of neutral scalar bosons in the compact 341 model, demonstrating compatibility with LHC data and analyzing potential signals of heavy scalars within theoretical constraints.

Contribution

It provides a detailed phenomenological analysis of neutral Higgs bosons in the compact 341 model, including signal strengths and branching ratios aligned with experimental data.

Findings

Predictions for $h_1$ signal strengths match LHC results.

Allowed parameter ranges for heavy scalars $h_2$ and $h_3$ are identified.

Branching ratios suggest potential discovery channels for heavy scalars.

Abstract

The phenomenology of the neutral scalar bosons in the compact 341 model is discussed. We show that the predictions of this model are fairly good and compatible with the experimental data by calculating the signal strength of $h_1$ for the channels $b\bar{b}$, W$W^{*}$, Z$Z^{*}$, $\tau\bar{\tau}$ and $\gamma\gamma$. Moreover, we use the branching ratios to search for the heavy neutral scalar bosons $h_2$ and $h_3$ where we take into account the theoretical constraints to precise the allowed ranges for the fundamental parameters of the scalar potential.
