Connecting Radiative Neutrino Mass, Neutron-Antineutron Oscillation, Proton Decay, and Leptogenesis through Dark Matter

TL;DR

This paper presents a unified theoretical framework linking radiative neutrino mass, neutron-antineutron oscillation, proton decay, and leptogenesis, with dark matter stability, advancing beyond the standard model of particle physics.

Contribution

It generalizes the scotogenic mechanism to incorporate multiple phenomena, providing a comprehensive model connecting neutrino mass, baryon number violation, and dark matter.

Findings

Unified description of neutrino mass and baryon number violation.

Dark matter stability via extended lepton parity.

Potential for leptogenesis within the framework.

Abstract

The scotogenic mechanism for radiative neutrino mass is generalized to include neutron-antineutron oscillation as well as proton decay. Dark matter is stabilized by extending the notion of lepton parity to matter parity. Leptogenesis is also a possible byproduct. This framework unifies the description of all these important, but seemingly unrelated, topics in physics beyond the standard model of particle interactions.
