Large magnetic dipole moments for neutrinos with arbitrary masses

TL;DR

This paper demonstrates models where neutrinos can possess large magnetic dipole moments without acquiring large masses, challenging conventional assumptions about neutrino properties.

Contribution

It introduces a class of models allowing large neutrino magnetic moments independently of their small masses.

Findings

Models with large neutrino magnetic moments are possible.

Examples of such models are provided.

Neutrino masses remain arbitrarily small in these models.

Abstract

We show that there is a general sort of models in which it is possible to have large magnetic dipole moments for neutrinos while keeping their masses arbitrarily small. Some examples of these models are considered.
