Gravitational Leptogenesis, Reheating, and Models of Neutrino Mass
Peter Adshead, Andrew J. Long, Evangelos I. Sfakianakis
Gravitational leptogenesis refers to a class of baryogenesis models in which the matter-antimatter asymmetry of the universe arises through the standard model lepton-number gravita…
Electroweak Sphaleron with Dimension-6 Operators
Xucheng Gan, Andrew J. Long, Lian-Tao Wang
New physics at the TeV scale can affect the dynamics of the electroweak phase transition in many ways. In this note, we evaluate its impact on the rate of baryon-number violation v…
Baryogenesis at a Lepton-Number-Breaking Phase Transition
Andrew J. Long, Andrea Tesi, Lian-Tao Wang
We study a scenario in which the baryon asymmetry of the universe arises from a cosmological phase transition where lepton-number is spontaneously broken. If the phase transition i…
