Primordial Leptogenesis
In this talk, I will present a framework that provides a mechanism to generate the baryon asymmetry of the universe through inflationary dynamics. I will introduce a minimal model where lepton and baryon asymmetries are generated during a reheating phase through the asymmetric decay of the inflaton field into SM Higgs bosons. This primordial lepton asymmetry is then converted to the baryon asymmetry through the electroweak sphaleron processes. Our mechanism offers an elegant UV completion of Dirac Leptogenesis.
