# A Froggatt-Nielsen flavor model for neutrino physics

## TL;DR

This paper presents a Froggatt-Nielsen flavor model integrated with the seesaw mechanism to explain neutrino masses and mixing, aligning with current experimental data and offering a simplified parameter framework.

## Contribution

It introduces a unified flavor model combining Froggatt-Nielsen and seesaw mechanisms, providing a consistent description of neutrino phenomenology with fewer parameters.

## Key findings

- Neutrino mass matrix consistent with experimental data
- Model predicts lepton number and flavor violation effects
- Simplified parameter space for neutrino phenomenology

## Abstract

Superheavy neutrinos can, via the seesaw model, provide a mechanism for lepton number violation. If they are combined with flavor violation as characterized by the Froggatt-Nielsen mechanism, then the phenomenology for the neutrinos in oscillation experiments, neutrinoless double beta decay, and other experiments can be described by a relatively few number of parameters. We describe the low-energy neutrino mass matrix and show that the results are consistent with currently available data.
