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…
The Higgs Boson can delay Reheating after Inflation
Katherine Freese, Evangelos I. Sfakianakis, Patrick Stengel +1
The Standard Model Higgs boson, which has previously been shown to develop an effective vacuum expectation value during inflation, can give rise to large particle masses during inf…
Higgsed Gauge-flation
Peter Adshead, Evangelos I. Sfakianakis
We study a variant of Gauge-flation where the gauge symmetry is spontaneously broken by a Higgs sector. We work in the Stueckelberg limit and demonstrate that the dynamics remain (…
