Relating Neutrino Masses by dilepton modes of Doubly Charged Scalars

TL;DR

This paper explores how measurements of dilepton decay modes of doubly charged scalars at colliders can reveal neutrino masses and Majorana phases within a two-loop Majorana neutrino mass model.

Contribution

It establishes explicit relationships between neutrino parameters and collider-detectable dilepton decay modes in a two-loop Majorana neutrino mass model.

Findings

Neutrino masses and Majorana phases can be extracted from dilepton decay measurements.

Explicit formulas relate neutrino parameters to collider observables.

The model connects neutrino physics with collider phenomenology.

Abstract

We study a model with Majorana neutrino masses generated through doubly charged scalars at two-loop level. We give explicit relationships between the neutrino masses and the same sign dilepton decays of the doubly charged scalars. In particular, we demonstrate that at the tribimaximal limit of the neutrino mixings, the absolute neutrino masses and Majorana phases can be extracted through the measurements of the dilepton modes at colliders.
