Neutrino Mass from Affleck-Dine Leptogenesis and WIMP Dark Matter

TL;DR

This paper proposes a unified model where lepton number breaking in the Affleck-Dine mechanism, combined with WIMP dark matter, generates neutrino mass at one loop, addressing inflation, baryogenesis, dark matter, and neutrino mass.

Contribution

It introduces a novel framework linking Affleck-Dine leptogenesis, WIMP dark matter, and neutrino mass generation at one loop.

Findings

Neutrino mass generated at one loop level.

Unified explanation for inflation, baryogenesis, dark matter, and neutrino mass.

Phenomenological implications discussed.

Abstract

Affleck-Dine (AD) mechanism for leptogenesis involves the cosmological evolution of a complex scalar field (AD field) that carries non-zero lepton number. We show how explicit lepton number breaking terms, which involve the AD field needed to implement this scenario combined with fermionic WIMP dark matter, can generate neutrino mass at the one loop level, thus providing a unified framework for solving four major puzzles of the standard model i.e. inflation, baryogenesis, dark matter and neutrino mass. We discuss some phenomenological implications of this model.
