# Generalized Bottom-Tau unification, neutrino oscillations and dark matter: predictions from a lepton quarticity flavor approach

## TL;DR

This paper presents an $A_4$ flavor model linking dark matter stability with neutrino properties, predicting specific mass relations, CP violation, and neutrino mass ordering, with implications for neutrino oscillation experiments.

## Contribution

It introduces a novel $A_4$ flavor extension of the Standard Model that correlates dark matter stability with neutrino Dirac nature and predicts specific neutrino oscillation parameters.

## Key findings

- Predicts a generalized bottom-tau mass relation involving all families.
- Induces small neutrino masses via a seesaw mechanism.
- Requires significant CP violation in neutrino oscillations.

## Abstract

We propose an $A_4$ extension of the Standard Model with a Lepton Quarticity symmetry correlating dark matter stability with the Dirac nature of neutrinos. The flavor symmetry predicts (i) a generalized bottom-tau mass relation involving all families, (ii) small neutrino masses are induced a la seesaw, (iii) CP must be significantly violated in neutrino oscillations, (iv) the atmospheric angle $\theta_{23}$ lies in the second octant, and (v) only the normal neutrino mass ordering is realized.
