Creating the Baryon Asymmetry from Lepto-Bubbles
Silvia Pascoli, Jessica Turner, Ye-Ling Zhou · Durham Research Online (Durham University) · 2017
We propose a new mechanism of baryogenesis which proceeds via a CP-violating phase transition. During this phase transition, the coupling of the Weinberg operator is dynamically realised and subsequently a lepton asymmetry is generated via the non-zero interference of this operator at different times. This new scenario of leptogenesis provides a direct connection between the baryon asymmetry, low energy neutrino parameters and leptonic flavour models.
