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.
Non-Gaussian primordial fluctuations of a Z2-symmetric spectator scalar trigger a strong first-order electroweak phase transition, with the field serving as cold dark matter and generating a stochastic gravitational wave background in the 10^{-3}-10^{-1} Hz band.
First-order gradient CP-violating sources in EWBG quantum transport relax electron EDM bounds and increase viability compared to prior approximations in a model illustration.
Collapsing axion-like domain walls generate the baryon asymmetry by acting as an effective chemical potential through coupling to the electroweak topological term, with the asymmetry produced via sphaleron processes.
Differences in filtering and delivery of rigid versus fragile dust to a planet-induced pressure bump reproduce carbonaceous chondrite compositions and ages in a single long-lived dust trap.
In weak first-order phase transitions, subcritical bubbles reach percent-level volume fractions before critical nucleation when phases are nearly degenerate at Tn, invalidating the homogeneous-background assumption for points satisfying log10 f̂_ξ(Tn) ≃ -1.95.
Nonlinear dynamics of a U(1)-breaking complex scalar field generates the observed baryon asymmetry from symmetric initial conditions, with late-time charge density scaling as t^{-3/2} via dynamical freeze-in.
In a B-L conserving SM extension with U(1)_x dark sector, CP-violating Yukawas generate opposite lepton asymmetries in visible and hidden sectors that sphalerons convert to baryon asymmetry, with gauge-independent bubble nucleation yielding stochastic GW spectra valid in supercooled regimes and a参数s
Deuterium-to-hydrogen measurements leave most electroweak baryogenesis parameter space unconstrained while imposing stronger exclusions on alternative baryogenesis models.
