The cosmological baryon asymmetry can be explained by the nonperturbative electroweak reprocessing of a lepton asymmetry generated in the out-of-equilibrium decay of heavy right-handed Majorana neutrinos. We analyze this mechanism in detail in the framework of a SO(10)-subgroup. We take three right-handed neutrinos into account and discuss physical neutrino mass matrices.

  1. Exploring Leptogenesis in the Era of First Order Electroweak Phase Transition

    hep-ph 2025-04 unverdicted novelty 6.0 of 10

    Low-scale leptogenesis becomes viable in the neutrino seesaw framework when a first-order electroweak phase transition allows sphalerons to convert lepton asymmetry into baryon asymmetry at temperatures below the Stan...

  2. Right-Handed Neutrino Production by an Axion-like Inflaton: Implications for Leptogenesis

    hep-ph 2026-07 conditional novelty 5.0 of 10

    A derivative-coupled axion-like inflaton can produce the heavy right-handed neutrinos whose decays explain the observed baryon asymmetry, with the required CP violation lower in the prompt-decay regime.

  3. Analytic formulation of Leptogenesis with neutrino oscillation data employing the general parametrization for neutrino mass matrix

    hep-ph 2025-06 conditional novelty 5.0 of 10

    Analytic CP asymmetry formulas from the Casas-Ibarra parametrization give minimum right-handed neutrino masses for successful leptogenesis, down to about 132 GeV with a neutrinophilic Higgs doublet and non-thermal production.

    Inverse-seesaw U(1)_{B-L} model correlates leptogenesis, Majorana DM relic density, and neutrino masses with collider signatures in dilepton and single-lepton channels.
