Neutrino masses from nonstandard supersymmetry breaking terms

TL;DR

This paper proposes a mechanism within minimal supersymmetry that naturally generates small Majorana neutrino masses through nonstandard breaking terms, potentially explaining proton decay without extra particles or scales.

Contribution

It introduces a novel approach to neutrino mass generation using nonstandard supersymmetry breaking terms without extending the particle content.

Findings

Small Majorana neutrino masses can arise naturally in minimal SUSY

The mechanism does not require additional particles or mass scales

It may also account for proton decay independently of GUTs

Abstract

Naturally small Majorana neutrino masses arise from nonstandard supersymmetry breaking terms. This mechanism works in the minimal supersymmetric framework and does not require extra particles or new mass scales. It could also be responsible for proton decay even in the absence of Grand Unification.
