Baryogenesis via leptonic CP-violating phase transition
  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.
