Baryogenesis via leptonic CP-violating phase transition.

Pascoli, Silvia and Turner, Jessica and Zhou, Ye-Ling (2018) 'Baryogenesis via leptonic CP-violating phase transition.', Physics letters B., 780 . pp. 313-318.


We propose a new mechanism to generate a lepton asymmetry based on the vacuum CP-violating phase transition (CPPT). This approach differs from classical thermal leptogenesis as a specific seesaw model, and its UV completion, need not be specified. The lepton asymmetry is generated via the dynamically realised coupling of the Weinberg operator during the phase transition. This mechanism provides a connection with low-energy neutrino observables.
