Models for neutrino mass and physics beyond standard model

TL;DR

This paper analyzes three-loop models of neutrino mass that incorporate dark matter, focusing on the Krauss-Nasri-Trodden (KNT) model, its viability, and potential experimental signals, while exploring related models within this class.

Contribution

It provides a detailed analysis of the KNT model's ability to address neutrino mass and dark matter, and introduces a broader class of similar three-loop models.

Findings

KNT model offers a viable solution to neutrino mass and dark matter problems.

The model predicts observable experimental signals.

A larger class of three-loop models related to KNT is identified.

Abstract

In this work, we report on recent analysis of three-loop models of neutrino mass with dark matter. We discuss in detail the model of Krauss-Nasri-Trodden (KNT) [1], showing that it offers a viable solution to the neutrino mass and dark matter problems, and describe observable experimental signals predicted by the model. Furthermore, we show that the KNT model belongs to a larger class of three-loop models that can differ from the KNT approach in interesting ways.
