The Little Review on Leptogenesis

TL;DR

This review discusses leptogenesis as a mechanism for baryogenesis, highlighting recent advances like flavor dynamics and resonant leptogenesis, which enable testable predictions at colliders and low-energy experiments.

Contribution

It summarizes recent developments in leptogenesis, emphasizing flavor effects and resonant scenarios near the electroweak scale, connecting theory with experimental prospects.

Findings

Recent models incorporate flavor dynamics for leptogenesis.

Resonant leptogenesis near the electroweak transition is phenomenologically viable.

Predictions can be tested at the LHC and in low-energy lepton-number violation experiments.

Abstract

This is a brief review on the scenario of baryogenesis through leptogenesis. Leptogenesis is an appealing scenario that may relate the observed baryon asymmetry in the Universe to the low-energy neutrino data. In this review talk, particular emphasis is put on recent developments on the field, such as the flavourdynamics of leptogenesis and resonant leptogenesis near the electroweak phase transition. It is illustrated how these recent developments enable the modelling of phenomenologically predictive scenarios that can directly be tested at the LHC and indirectly in low-energy experiments of lepton-number and lepton-flavour violation.
