These lectures provide a pedagogical review of the present status of theories explaining the observed baryon asymmetry of the Universe. Particular emphasis is given on GUT baryogenesis and electroweak baryogenesis. The key issues, the unresolved problems and the very recent developments, such as GUT baryogenesis during preheating, are explained. Some exercises (and their solution) are also provided.

  1. Primordial Neutron Stars

    astro-ph.CO 2026-04 unverdicted novelty 6.0

    Large initial baryon asymmetry allows Hubble patches to collapse into primordial neutron stars arrested by nuclear pressure, requiring later entropy dilution to match observed Y_B and BBN.

  2. Einstein-Cartan pseudoscalaron inflation, reheating and nonthermal leptogenesis

    astro-ph.CO 2026-05 unverdicted novelty 5.0

    Einstein-Cartan pseudoscalaron inflation coupled to type-I seesaw neutrinos makes nonthermal leptogenesis a necessary mechanism for the baryon asymmetry, yielding ns ~ 0.97, r ~ 0.004 and nB/s ~ 8.7e-11 for gamma ~ -1...

  3. Probing CP Violation with Hyperon EDMs at BESIII

    hep-ex 2026-04 unverdicted novelty 2.0

    Review of hyperon EDM searches via modular angular analysis at BESIII, reporting a three-order-of-magnitude improvement in the upper limit on the Lambda EDM.

  4. Bounds from D/H on baryogenesis models

    hep-ph 2026-04 unverdicted novelty 2.0

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