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.

An axion-like particle's domain wall or shock wave induces an electroweak phase boundary whose motion creates a local B+L chemical potential that biases active sphalerons to generate net baryon asymmetry.
Radiative electroweak symmetry breaking with a logarithmic potential yields analytical vacuum solutions, four thermal history patterns, and supercooled FOPT gravitational waves whose signals combined with collider data can probe conformal scales to 10^5-10^8 GeV.
Deuterium-to-hydrogen measurements leave most electroweak baryogenesis parameter space unconstrained while imposing stronger exclusions on alternative baryogenesis models.
