# Lepton Flavor Violation and Neutrino Masses from $A_5$ and CP in the Non-Universal MSSM

## TL;DR

This paper explores how an $A_5$ and CP flavor symmetry embedded in a supersymmetric model influences lepton flavor violation and neutrino masses, providing testable predictions for observable phenomena.

## Contribution

It introduces a novel framework combining $A_5$ and CP symmetries in SUSY to analyze lepton flavor violation and neutrino mass generation with specific residual symmetries.

## Key findings

- Predicts specific patterns in neutrino spectrum and mixing
- Identifies unavoidable flavor violation effects in charged leptons
- Provides relations among observables for experimental tests

## Abstract

We analyze the phenomenological consequences of embedding a flavor symmetry based on the groups $A_5$ and CP in a supersymmetric framework. We concentrate on the leptonic sector, where two different residual symmetries are assumed to be conserved at LO for charged and neutral leptons. All possible realizations to generate neutrino masses at tree level are investigated. Sizable flavor violating effects in the charged lepton sector are unavoidable due to the non-universality of soft-breaking terms determined by the symmetry. We derive testable predictions for the neutrino spectrum, lepton mixing and flavor changing processes with non-trivial relations among observables.
