Neutrinoless double beta decay mediated by the neutrino magnetic moment

TL;DR

This paper proposes a novel mechanism for neutrinoless double beta decay involving neutrino interactions with a rotating magnetic field, potentially affecting decay half-life measurements.

Contribution

It introduces a new decay channel where neutrinos interact with a rotating magnetic field, expanding understanding of possible decay processes.

Findings

Half-life of neutrinoless double beta decay can be significantly reduced.

Neutrino interactions with external magnetic fields influence decay rates.

Rotating magnetic fields may serve as a new experimental parameter.

Abstract

We present a new channel of the neutrinoless double beta decay. In this scenario neutrinos not only oscillate inside the nucleus but also interact with an external non-uniform magnetic field. We assume that the field rotates about the direction of motion of the neutrino and show, that for a certain speed of rotation the half-life of the $0\nu2\beta$ decay may be significantly lowered.
