Compatibility of gravitational baryogenesis in f(Q, C) gravity

European Physical Journal C: Particles and Fields
This paper investigates the disparity between matter and antimatter in the universe with the help of gravitational baryogenesis. This phenomenon commenced shortly after the big bang, resulting in a predominance of matter over antimatter.

Baryogenesis in the MSSM, nMSSM and NMSSM

, 2006
We compare electroweak baryogenesis in the MSSM, nMSSM and NMSSM. We comment on the different sources of CP violation, the phase transition and constraints from EDM measurements.We compare electroweak baryogenesis in the MSSM, nMSSM and NMSSM. We comment

Spectator processes and baryogenesis

, 2001
Spectator processes which are in thermal equilibrium during the period of baryogenesis influence the final baryon asymmetry. We study this effect quantitatively for thermal leptogenesis where we find a suppression by a factor O(1)

Baryogenesis via leptogenesis

, 2019
This thesis explores the question of the matter-antimatter asymmetry in our current observable universe, which is the baryogenesis problem. We review the standard model and show that, despite the model being able to host conditions necessary for ...

Resonant relaxation in electroweak baryogenesis [PDF]

, 2005
We compute the leading, chiral charge-changing relaxation term in the quantum transport equations that govern electroweak baryogenesis using the closed time path formulation of nonequilibrium quantum field theory.

Electron electric dipole moment and electroweak baryogenesis in a complex singlet extension of the Standard Model with degenerate scalars

Physics Letters B
We study the possibility of electroweak baryogenesis in the standard model with a complex scalar field, focusing mainly on a degenerate scalar scenario.

Recent Developments in Electroweak baryogenesis

, 1998
We discuss some recent developments made in the computation of the baryon asymmetry generated at the electroweak scale. We emphasize that the local number density asymmetries of the particles involved in supersymmetric electroweak baryogenesis must be ...

An effective approach to electroweak baryogenesis

, 2020
The asymmetry between matter and antimatter is one of the big outstanding questions of particle physics and cosmology. In this talk, I will argue that electroweak baryogenesis is an interesting mechanism to generate the baryon asymmetry.
