Differentiating Neutrino Models on the Basis of $\theta_{13}$ and Lepton Flavor Violation

TL;DR

This paper compares different neutrino mass models based on their predictions for the mixing angle θ13 and lepton flavor violation processes, highlighting how these observables can distinguish between models.

Contribution

It demonstrates how to differentiate neutrino models using predictions for θ13 and lepton flavor violation, with detailed analysis of five SO(10) SUSY GUT models.

Findings

Lepton flavor violation varies significantly across models.

Heavy right-handed neutrino spectra influence flavor violation predictions.

Predictions for θ13 are crucial for model differentiation.

Abstract

We show how models of neutrino masses and mixings can be differentiated on the basis of their predictions for $\theta_{13}$ and lepton flavor violation in radiative charged lepton decays and $\mu - e$ conversion. We illustrate the lepton flavor violation results for five predictive SO(10) SUSY GUT models and point out the relative importance of their heavy right-handed neutrino mass spectra and $\theta_{13}$ predictions.
