abstract
Although the origin of matter-antimatter asymmetry remains unknown, continuing advances in theory and improved experimental limits have ruled out some scenarios for baryogenesis, for example the sphaleron baryogenesis at the electroweak phase transition in the standard model. At the same time, the success of cosmological inflation and the prospects for discovering supersymmetry at the LHC have put some other models in sharper focus. We review the current state of our understanding of baryogenesis with the emphasis on those scenarios that we consider most plausible.

Filtered Dark Matter hydrodynamics during first-order phase transitions is modeled as a two-component fluid, yielding detonation-like and deflagration-like solutions in ballistic and local thermal equilibrium regimes that change relic abundance predictions.
The mass ranges for the dark antibaryon ψ_DS are determined by deriving the B_d → Λ ψ_DS branching fraction via light-cone QCD sum rules and comparing it to BaBar and Belle experimental bounds.
A globally CPT-symmetric paired-universe model with local violations produces inflaton mass splitting that modifies reheating and accounts for observed matter-antimatter asymmetry.
Two scalar-nonmetricity gravity models reproduce the observed baryon asymmetry for gamma values of 0.2-0.3 and reasonable alpha, beta parameters.
Deuterium-to-hydrogen measurements leave most electroweak baryogenesis parameter space unconstrained while imposing stronger exclusions on alternative baryogenesis models.
