Quantum Transport and Electroweak Baryogenesis
, 2013 We review the mechanism of electroweak baryogenesis. Our focus is on the derivation of quantum transport equations from first principles within the Schwinger–Keldysh formalism.

Electroweak Baryogenesis and Higgs Properties [PDF]
, 2012 We explore the connection between the strength of the electroweak phase transition and the properties of the Higgs boson. Our interest is in regions of parameter space that can realize electroweak baryogenesis. We do so in a simplified framework in which

Nambu-Goldstone Affleck-Dine baryogenesis
Journal of High Energy Physics, 2019 The Affleck-Dine mechanism creates the baryon asymmetry of the universe from an angular motion of a complex scalar field. The mechanism is efficient and allows for a low reheating temperature of the universe if the scalar field has a flat potential along

Electroweak Baryogenesis – A Status Report
, 2013 We review the mechanism of electroweak baryogenesis. In the light of recent electric dipole moment measurements and given the results on new physics searches from collider experiments, the status of electroweak baryogenesis is discussed in a variety of ...

Low-scale baryogenesis from three-body decays [PDF]
Baryogenesis at the TeV scale from CP-violating decays of a massive particle requires some way to avoid the washouts from processes closely related to the existence of CP violation.

High scale electroweak phase transition: baryogenesis & symmetry non-restoration
Journal of High Energy Physics, 2018 We explore the possibility that the electroweak phase transition happens at a scale much higher than the electroweak scale today. In this context, high scale CP-violating sources for electroweak baryogenesis are not constrained by low-energy experiments.

Scalar–tensor baryogenesis: a scalar–tensor completion of gravitational baryogenesis
Physics Letters BWe propose Scalar–Tensor Baryogenesis (STB), in which the CP-violating bias needed for baryogenesis is sourced by the gravitational scalars that appear in scalar–tensor representations of modified gravity.

Varying constants driven baryogenesis
European Physical Journal C: Particles and Fields, 2019 We study the spontaneous baryogenesis scenario in the early universe for three different frameworks of varying constants theories. We replace the constants by dynamical scalar fields playing the role of thermions.
