Leptonic CP violation

TL;DR

This paper reviews CP violation in the lepton sector, focusing on theoretical models, observable effects in experiments, and implications for the universe's matter-antimatter asymmetry.

Contribution

It provides a comprehensive overview of leptonic CP violation, emphasizing seesaw models, experimental observables, and cosmological implications.

Findings

CP violation affects neutrino oscillations and neutrinoless double beta decay.

Leptonic CP violation could explain the baryon asymmetry of the Universe.

Potential signals of leptonic CP violation in collider experiments like the LHC.

Abstract

Several topics on CP violation in the lepton sector are reviewed. A few theoretical aspects concerning neutrino masses, leptonic mixing, and CP violation will be covered, with special emphasis on seesaw models. A discussion is provided on observable effects which are manifest in the presence of CP violation, particularly, in neutrino oscillations and neutrinoless double beta decay processes, and their possible implications in collider experiments such as the LHC. The role that leptonic CP violation may have played in the generation of the baryon asymmetry of the Universe through the mechanism of leptogenesis is also discussed.
