An explicit model generates the observed baryon asymmetry via annihilogenesis of right-handed neutrinos confined in false-vacuum pockets during a strong first-order phase transition, relaxing the usual light-neutrino-mass upper bound on the CP asymmetry.

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 Standard Model decoupling point.
