Left-Right Symmetry: from LHC to Neutrinoless Double Beta Decay

TL;DR

This paper explores how LHC data on left-right symmetry and lepton flavor violation can predict neutrinoless double beta decay rates, focusing on the type-II seesaw mechanism.

Contribution

It demonstrates a method to connect collider measurements and rare decay processes to understand neutrino mass mechanisms.

Findings

LHC can probe left-right symmetry restoration scale.

Constraints from lepton flavor violation inform neutrinoless double beta decay predictions.

Type-II seesaw provides a specific framework for these connections.

Abstract

The Large Hadron Collider has a potential to probe the scale of left-right symmetry restoration and the associated lepton number violation. Moreover, it offers hope of measuring the right-handed leptonic mixing matrix. We show how this, together with constraints from lepton flavor violating processes, can be used to make predictions for neutrinoless double beta decay. We illustrate this deep connection in the case of the type-II seesaw.
