Baryogenesis from the weak scale to the grand unification scale
Dietrich Bödeker, W. Buchmüller
Abstract
The standard model of elementary particle physics, once augmented with Sakharov's conditions, offers several scenarios to explain today's matter-antimatter asymmetry. This survey evaluates the paths to baryogenesis. Of special interest is that time-reversal violation in neutrino physics, together with large mixings, seems poised to produce the observed asymmetry via leptogenesis. This review occurs at a time when several experiments are on the threshold of a precise measurement of time violation in lepton mixing.
