We present the relation between the sphaleron energy and the gravitational wave signals from a first order electroweak phase transition. The crucial ingredient is the scaling law between the sphaleron energy at the temperature of the phase transition and that at zero temperature. We estimate the baryon number preservation criterion, and observe that for a sufficiently strong phase transition, it is possible to probe the electroweak sphaleron using measurements of future space-based gravitational wave detectors.

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

    hep-ph 2026-07 conditional novelty 5.0

    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.

  2. Electroweak phase transition in SMEFT: Gravitational wave and collider complementarity

    hep-ph 2025-12 conditional novelty 5.0

    Strong first-order electroweak phase transitions in dimension-6 SMEFT can be probed by future gravitational wave detectors and by di-Higgs production at the HL/HE-LHC, with correlated sensitivity regions.
