The dynamics of the electroweak phase transition in the early universe has profound implications for cosmology and particle physics. We systematically study the steady-state dynamics of bubble walls in scenarios where the transition is first order within three representative beyond the Standard Model frameworks, characterised by the presence of an additional scalar in different electroweak representations. Focusing on the local thermal equilibrium regime, we numerically solve the coupled scalar and hydrodynamic equations to extract key properties of the phase transition front: the wall velocity, width, plasma and field profiles. Remarkably, we find a near-universal behaviour across models when expressed in terms of thermodynamic quantities, that can be captured by simple fitting functions, useful for phenomenological applications. These results also provide an upper bound on the bubble velocity and represent the first necessary step for the full inclusion of out-of-equilibrium effects.

  1. Entropy production at electroweak bubble walls from scalar field fluctuations

    hep-ph 2025-07 conditional novelty 7.0 of 10

    Scalar fluctuations produce a nonvanishing entropy discontinuity across an electroweak bubble wall even in the zero-friction limit, showing LTE-based wall velocity upper bounds cannot be saturated.

  2. Multi-step Strong First-Order Electroweak Phase Transitions in the Inverted Type-I 2HDM: Parameter Space, Gravitational Waves, and Collider Phenomenology

    hep-ph 2025-06 conditional novelty 7.0 of 10

    In the inverted Type-I 2HDM, one-step and two-step strong first-order electroweak phase transitions live in largely separate parameter regions, and LISA-detectable gravitational wave signals come predominantly from th...

  3. Theoretical uncertainties in reconstructing model parameters with gravitational waves from supercooled phase transitions

    hep-ph 2026-07 conditional novelty 6.0 of 10

    In the conformal U(1)_X model, the daisy-resummed nucleation scheme shifts LISA-reconstructed gauge couplings by O(10%) relative to the NLO effective-field-theory result, an order of magnitude above the Fisher-matrix ...

  4. Thermal Masses and Bubble-Wall Friction in Cosmological Phase Transitions

    hep-ph 2026-07 conditional novelty 6.0 of 10

    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.

    hep-ph 2026-07 accept novelty 6.0 of 10

    In the Normal 2HDM, SFOEWPTs are single-step and alignment-favoring across all four Yukawa types, yet Parwani versus Arnold–Espinosa resummation changes the viable heavy-mass range from ~1.6 TeV to ≲800 GeV and leaves...

  6. Electroweak Baryogenesis: Advances in Sphaleron Rate Calculations and Implications of Thermal Phase Transitions

    hep-ph 2026-07 conditional novelty 5.0 of 10

    Sphaleron rates can be computed gauge-invariantly in 3D thermal EFT, yielding a new baryon-washout criterion x = lambda3/g3^2 that replaces v_c/T_c > 1 for electroweak baryogenesis.

  7. Machine Learning Left-Right Breaking from Gravitational Waves

    An ML-guided scan combined with a high-precision effective field theory finds a small region of the minimal Left-Right Symmetric Model where the first parity-breaking phase transition yields gravitational waves detect...
