Some aspects of baryogenesis and lepton number violation

TL;DR

This paper reviews the relationship between baryogenesis, lepton number violation, and neutrino properties, focusing on cosmological bounds, leptogenesis, and dark matter implications within the standard model context.

Contribution

It provides a comprehensive review of how neutrino properties influence baryogenesis and lepton number violation, highlighting recent cosmological constraints and theoretical implications.

Findings

Cosmological bounds constrain neutrino masses.

Leptogenesis mechanisms are linked to baryon asymmetry.

Implications for dark matter are discussed.

Abstract

The cosmological baryon asymmetry is closely related to neutrino properties due to the non-perturbative sphaleron processes in the high-temperature symmetric phase of the standard model. We review some aspects of this connection with emphasis on cosmological bounds on neutrino masses, leptogenesis and possible implications for dark matter.
