Baryogenesis and leptogenesis

talk (15min)

The observed baryon asymmetry of the Universe provides a fundamental probe of high-scale physics and the thermal history of the electroweak plasma. Within the Standard Model, sphaleron processes partially convert a primordial $B-L$ asymmetry into baryon number, and the corresponding sphaleron conversion factor is a key ingredient in quantitative predictions of baryogenesis scenarios.
