The cosmological baryon asymmetry can be explained as remnant of heavy Majorana neutrino decays in the early universe. We study this out-of-equilibrium process by means of Kadanoff-Baym equations which are solved in a perturbative expansion. To leading order the problem is reduced to solving a set of Boltzmann equations for distribution functions.

  1. Tachyonic particle production: quantum 2PI formalism with momentum exchanging collisions

    hep-ph 2026-06 unverdicted novelty 6.0 of 10

    Presents a self-consistent reduction of non-local next-to-leading-order 2PI equations to local quantum kinetic equations that incorporate momentum exchange during tachyonic instabilities.

  2. Forbidden neutrinogenesis

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A neutrinophilic two-Higgs-doublet model with Dirac neutrinos can generate the observed baryon asymmetry through finite-temperature 'forbidden' leptogenesis, favoring normal neutrino mass ordering and 0 < δ_CP < π.
