CP Violation in the Lepton Sector and Implications for Leptogenesis
read the original 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).

The Majoron Cosmological Window: Dark Matter and Thermal Leptogenesis
The minimal majoron framework permits simultaneous majoron dark matter and thermal leptogenesis in a constrained cosmological window set by freeze-in production, warm dark matter bounds, and indirect detection limits.

When Does Leptogenesis Survive Lepton Flavor Violation Constraints? High- and Low-Scale Realizations in the Scotogenic Model
High-scale leptogenesis in the scotogenic model decouples from LFV bounds and remains viable, while low-scale resonant leptogenesis is viable only in a narrow parameter region with suppressed flavor violation.
