It is widely believed that electroweak baryogenesis should be suppressed in strong phase transitions with fast-moving bubble walls, but this effect has never been quantitatively studied. We rederive fluid equations describing transport of particle asymmetries near the bubble wall without making the small-wall-velocity approximation. We show that the suppression of the baryon asymmetry is a smooth function of the wall speed and that there is no special behavior when crossing the sound speed barrier. Electroweak baryogenesis can thus be efficient also with strong detonations, generically associated with models with observably large gravitational waves. We also make a systematic and critical comparison of our improved transport equations to another one commonly used in the literature, based on the VEV-insertion formalism.

An Effective Sphaleron Awakens
A consistent 3D EFT computation of the Higgs phase sphaleron rate yields universal baryon preservation bounds x ≈ 0.025 (strong) and x ≈ 0.036 (weak), and shows two-loop corrections eliminate strong one-step transitio...

Benchmarking wall velocities in cosmological phase transitions: Fluid Ansatz and WallGo
The fluid-Ansatz and WallGo methods agree for mild phase transitions but diverge by tens of percent for strong ones, where the semi-classical approximation itself may break down.

Thermal Masses and Bubble-Wall Friction in Cosmological Phase Transitions
Including thermal masses in both the Boltzmann source and collision terms removes the infrared gauge-boson enhancement, making W-boson friction subleading in the singlet-extended Standard Model.

DMRadio-Core: A new approach for GUT-scale axion searches
Electroweak-symmetric domain walls produce the observed baryon asymmetry when CP-odd sources and the hierarchy of wall, source, and diffusion lengths suppress face-to-face cancellation.

Dark Sector Electroweak Baryogenesis In Light Of The Galactic Center Excess
A dark-sector electroweak baryogenesis model with a ~50 GeV fermionic dark matter candidate can simultaneously match the baryon asymmetry, the dark matter relic density, and (at ~2 sigma) the galactic center gamma-ray...
