CP violation and baryogenesis
W. Bernreuther
TL;DR
This paper reviews theories and mechanisms explaining the universe's matter-antimatter asymmetry, focusing on electroweak baryogenesis, GUT baryogenesis, and leptogenesis, connecting cosmology and particle physics.
Contribution
It provides an overview of various baryogenesis scenarios, highlighting their theoretical foundations and potential to explain matter-antimatter asymmetry.
Findings
Electroweak baryogenesis offers a viable mechanism under certain conditions.
GUT baryogenesis involves grand unified theories to generate asymmetry.
Leptogenesis links neutrino physics to matter-antimatter asymmetry.
Abstract
In these lecture notes an introduction is given to some ideas and attempts to understand the origin of the matter-antimatter asymmetry of the universe. After the discussion of some basic issues of cosmology and particle theory the scenarios of electroweak baryogenesis, GUT baryogenesis, and leptogenesis are outlined.
