# A 3-3-1 model with low scale seesaw mechanisms

## TL;DR

This paper proposes a comprehensive 3-3-1 model incorporating low-scale seesaw mechanisms, family symmetries, and extended fermion spectra to explain fermion masses, mixing, and flavor phenomena consistent with current experimental data.

## Contribution

It introduces a novel 3-3-1 framework combining multiple seesaw mechanisms and symmetries to address fermion mass hierarchies and flavor violations.

## Key findings

- Model aligns with SM fermion flavor data
- Predicts charged lepton flavor violation within experimental reach
- Accommodates observed Higgs diphoton decay rate

## Abstract

We construct a viable 3-3-1 model with two $SU(3)_L$ scalar triplets, extended fermion and scalar spectrum, based on the $T^{\prime}$ family symmetry and other auxiliary cyclic symmetries, whose spontaneous breaking yields the observed pattern of SM fermion mass spectrum and fermionic mixing parameters. In our model the SM quarks lighter than the top quark, get their masses from a low scale Universal seesaw mechanism, the SM charged lepton masses are produced by a Froggatt-Nielsen mechanism and the small light active neutrino masses are generated from an inverse seesaw mechanism. The model is consistent with the low energy SM fermion flavor data and successfully accommodates the current Higgs diphoton decay rate and predicts charged lepton flavor violating decays within the reach of the forthcoming experiments.
