## TL;DR

This paper investigates CP violation in the scalar sector of a 331 model with SU(3) symmetry, focusing on spontaneous CP violation with a single CP phase and analyzing scalar mass states.

## Contribution

It introduces a specific 331 model with a discrete symmetry that enables spontaneous CP violation with one independent phase, expanding understanding of CP violation mechanisms.

## Key findings

- Identified conditions for spontaneous CP violation in the model
- Derived scalar mass eigenstates and their rotations
- Provided a framework for analyzing CP violation in extended gauge models

## Abstract

In order to understand some frameworks for CP Violation scenarios in the scalar sector, a 331 model was considered which its main property is the incorporation of a local group symmetry SU(3) in the electroweak sector. In particular, a 331 model with a particular choice of free parameter. CP Violation scenarios were obtained by introducing a discrete symmetry in the scalar triplets, which exhibit a spontaneous CP Violation frame with just one independent CP phase associated. Mass state rotations were obtained.
