CP Violation in the Lepton Sector and Implications for Leptogenesis

TL;DR

This paper reviews the current understanding of CP violation in the lepton sector, its measurement prospects, and its potential role in explaining the matter-antimatter asymmetry through leptogenesis within seesaw models.

Contribution

It highlights the connection between low-energy CP violation phases and leptogenesis in models with flavor and CP symmetries, emphasizing recent theoretical developments.

Findings

Current data on neutrino masses and mixing are summarized.

Prospects for measuring CP-violating phases are discussed.

Theoretical links between CP violation and leptogenesis are explored.

Abstract

We review the current status of the data on neutrino masses and lepton mixing and the prospects for measuring the CP-violating phases in the lepton sector. The possible connection between low energy CP violation encoded in the Dirac and Majorana phases of the Pontecorvo-Maki-Nakagawa-Sakata mixing matrix and successful leptogenesis is emphasized in the context of seesaw extensions of the Standard Model with a flavor symmetry Gf (and CP symmetry).
