Electric charge quantization in SU(3)XSU(4)XU(1) models

TL;DR

This paper demonstrates electric charge quantization within SU(3)×SU(4)×U(1) models by analyzing symmetry and anomaly conditions, considering three-family models with scalar fields for symmetry breaking.

Contribution

It introduces a method to achieve charge quantization in extended gauge models using classical and quantum anomaly conditions.

Findings

Charge quantization is achieved in the SU(3)×SU(4)×U(1) framework.

Anomaly cancellation constrains the model parameters.

Scalar fields facilitate spontaneous symmetry breaking.

Abstract

We obtain electric charge quantization in the context of models based on the gauge symmetry group SU(3) X SU(4) X U(1). The gauge models studied include three families to cancel out anomalies and a set of scalar fields to break spontaneously the symmetry. To show the electric charge quantization, we use clasical symmetry conditions and quantum quiral anomaly conditions.
