Theories of Baryogenesis [PDF]
These lectures provide a pedagogical review of the present status of theories explaining the observed baryon asymmetry of the Universe. Particular emphasis is given on GUT baryogenesis and electroweak baryogenesis. The key issues, the unresolved problems
Riotto, Antonio
core
The standard model of particle physics describes matter and antimatter as coming from the same fields and this fact has been confirmed experimentally. It is then curious that the observable universe is made of matter and not antimatter. We will first discuss the evidence that we live in a matter-dominated (or matter-antimatter asymmetric) Universe and ...

Gravitational Baryogenesis in Energy-Momentum Squared Gravity
We demonstrate that the matter sector itself can drive baryogenesis in energy-momentum squared gravity, f(R,T2) with T2≡TμνTμν. High-density matter corrections provide new time-dependent sources for the baryon asymmetry through derivative couplings to T2

Phase transitions and baryogenesis from decays
We study scenarios in which the baryon asymmetry is generated from the decay of a particle whose mass originates from the spontaneous breakdown of a symmetry.

Baryogenesis through leptogenesis
Baryogenesis by heavy-neutrino decay and sphaleron reprocessing of both baryon and lepton number is reconsidered, paying special attention to the flavour structure of the general evolution equations and developing an approximate but sufficiently accurate

Baryogenesis and low energy CP violation [PDF]
CP violation is a crucial component in the creation of the matter - anti matter asymmetry of the universe. An important open question is whether the CP violating phenomena observeable in terrestrial experiments have any relation with those responsible ...

Electroweak baryogenesis driven by extra top Yukawa couplings
We study electroweak baryogenesis driven by the top quark in a general two Higgs doublet model with flavor-changing Yukawa couplings, keeping the Higgs potential CP invariant.

Spontaneous baryogenesis from asymmetric inflaton
We propose a variant scenario of spontaneous baryogenesis from asymmetric inflaton based on current–current interactions between the inflaton and matter fields with a non-zero B−L charge.
