Recent Progress in Baryogenesis
read the original abstract
We provide an up to date account of progress in understanding the origin of the observed baryon asymmetry of the universe. While our primary goal is to be current, we have attempted to give a pedagogical introduction to the primary areas of research in this field, giving a detailed description of the different scenarios. The very recent developments in GUT baryogenesis, leptogenesis, electroweak baryogenesis and the Affleck-Dine mechanism are presented. In particular, we focus on specific particle physics implementations, mostly in the context of supersymmetry, which lead to specific testable predictions.

Electroweak Baryogenesis from Collapsing Domain Walls
Collapsing axion-like domain walls generate the baryon asymmetry by acting as an effective chemical potential through coupling to the electroweak topological term, with the asymmetry produced via sphaleron processes.

Mass of the dark antibaryon using $B_d\rightarrow \Lambda \psi_{DS}$ channel in light cone QCD
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.

Searching for apparent baryon number violation in $\Lambda_c^+$ decays at the Super Tau-Charm Facility
STCF with 1 ab^{-1} can probe several-TeV new-physics scales in sterile-neutrino EFT and constrain an RPV SUSY parameter to ~0.1 TeV^{-2} for apparent BNV in unexplored Lambda_c+ channels.

Gravitational baryogenesis in scalar-nonmetricity $f(Q,\phi)$ gravity
Two scalar-nonmetricity gravity models reproduce the observed baryon asymmetry for gamma values of 0.2-0.3 and reasonable alpha, beta parameters.

A proof-of-principle experiment on the spontaneous symmetry breaking machine and numerical estimation of its performance on the $K_{2000}$ benchmark problem
The spontaneous symmetry breaking machine converges to one extremely stable state in small-scale experiments and K2000 numerical simulations, offering a potential advantage over other optimization simulators.

Bounds from D/H on baryogenesis models
Deuterium-to-hydrogen measurements leave most electroweak baryogenesis parameter space unconstrained while imposing stronger exclusions on alternative baryogenesis models.
