Developments in understanding of baryogenesis are reviewed. We start with early motivations and the proposals in the context of GUTs. Next, the importance of the sphaleron solution and its implications are discussed. Studies of the Standard Model reveal that the latter has a Higgs structure incompatible with existence of observed B asymmetry. We then discuss a generic scenario for electroweak baryogenesis relying on bubble wall dynamics. We also summarise the status of the MSSM, and alternative scenarios utilising topological defects as the source of non-equilibrium behaviour and leptogenesis

• Gravitational probes of dark matter physics (2017, background): “This requires annihilation cross sections in the early Universe at least as large as those of a thermal relic [52], and so Λ−1ADM & 5× 10 −5 GeV−1.”
• Primordial black holes as dark matter candidates (2021, background): “For a PBH formed at T ≈ ΛQCD ≈ 140MeV, the effective temperature is Teff = 2 E0/3 ≈ 5TeV, which is well above the sphaleron barrier and induces a charge-parity violation parameter δCP(T ) ∼ 10−5 (T/20GeV)−12 [242].”
