Leptogenesis at the Electroweak Scale

TL;DR

This paper proposes a leptogenesis model where the heavy neutral lepton mass scale is close to the electroweak symmetry breaking scale, offering a novel approach to explaining matter-antimatter asymmetry.

Contribution

It introduces a new leptogenesis model with heavy neutral leptons at the electroweak scale, differing from traditional high-scale models.

Findings

Model successfully generates lepton asymmetry at electroweak scale

Potential testability at current collider energies

Provides a link between leptogenesis and electroweak physics

Abstract

In this note we propose a model of leptogenesis in which the scale for the mass of the necessary heavy neutral lepton is similar to the scale of electroweak symmetry breaking.
