Radiatively Induced Neutrino Majorana Masses and Oscillation

TL;DR

This paper reviews models where neutrino Majorana masses are generated through radiative processes, explaining neutrino oscillations and predicting observable rare decay phenomena.

Contribution

It highlights the capability of these models to account for neutrino oscillations and predicts potential observable rare decay processes like neutrinoless double beta decay.

Findings

Models can explain solar and atmospheric neutrino oscillations.

Some models predict observable neutrinoless double beta decay.

Potential for observing $^-$ -- $e^+$ conversion in nuclei.

Abstract

We review and remark on models of radiatively induced neutrino Majorana masses and oscillations. It is pointed out that while the models are capable of accounting for the observed solar and atmospheric neutrino oscillation, some of them can also induce neutrinoless double beta decay and $\mu^-$ -- $e^+$ conversion in nuclei large enough to be potentially observable in the near future.
