Simple Left-Right Theory: Lepton Number Violation at the LHC

TL;DR

This paper introduces a minimal left-right symmetric model where neutrino masses are generated quantum mechanically, predicting lepton number violation signatures at the LHC for experimental testing.

Contribution

It presents a simple, minimal scalar sector left-right symmetric theory with neutrino masses generated at the quantum level and explores its testable lepton number violating signatures at the LHC.

Findings

Neutrinos are Majorana fermions in the model.

Lepton number violation signatures involve two charged leptons of different flavor and missing energy.

The model's signatures are accessible for testing at the LHC.

Abstract

We propose a simple left-right symmetric theory where the neutrino masses are generated at the quantum level. In this context the neutrinos are Majorana fermions and the model has the minimal degrees of freedom in the scalar sector needed for symmetry breaking and mass generation. We discuss the lepton number violating signatures with two charged leptons of different flavor and missing energy at the Large Hadron Collider in order to understand the testability of the theory.
