# Lepton Flavour Violation in Left-Right Theory

## TL;DR

This paper explores lepton flavor violation in a left-right symmetric model with Majorana neutrinos, highlighting potential observable signals in rare decays and collider experiments.

## Contribution

It introduces a simple left-right symmetric framework with radiatively generated neutrino masses and analyzes its testable predictions for lepton number violating processes.

## Key findings

- Right-handed neutrinos are typically light.
- Large contributions to mu to e gamma and mu to e conversion are possible.
- Collider constraints can be combined with rare decay predictions for testing.

## Abstract

We investigate the predictions for lepton flavour number violating processes in the context of a simple left-right symmetric theory. In this context neutrinos are Majorana fermions and their masses are generated at the quantum level through the Zee mechanism using the simplest Higgs sector. We show that the right handed neutrinos are generically light and can give rise to large lepton number violating contributions to rare processes. We discuss the correlation between the collider constrains and the predictions for lepton number violating processes. We find that using the predictions for mu to e gamma and mu to e conversion together with the collider signatures one could test this theory in the near future.
