We reexamine production of primordial black holes in a supercooled phase transition. While a mere overdensity associated with a surviving false-vacuum patch does not imply formation of a black hole, it is possible for such a patch to evolve and create a black hole, thanks to the gradient energy stored in the bubble wall.

Discussion (0). Continue with ORCID to comment.

  1. Can the universe be matter-dominated after a supercooled first-order phase transition?

    hep-ph 2026-07 conditional novelty 7.0 of 10

    After a supercooled first-order phase transition, the scalar field's equation of state is set by the bubble-wall Lorentz factor γ*, and matter domination is delayed until a/a* ≃ γ* in the free-streaming limit.

  2. Numerical simulations of primordial black hole formation via delayed first-order phase transitions

    gr-qc 2026-01 conditional novelty 6.0 of 10

    Spherically symmetric numerical relativity shows false-vacuum domains from delayed first-order phase transitions form type B (baby-universe) or type A (direct-collapse) primordial black holes, separated by a robust t_...

  3. Complementarity of gravitational wave analyses and di-Higgs production in the exploration of the Electroweak Phase Transition dynamics in the RxSM

    hep-ph 2025-10 conditional novelty 6.0 of 10

    In the real singlet extension of the SM, strong first-order electroweak phase transitions split into singlet-driven transitions (loud in gravitational waves, quiet at colliders) and doublet-driven transitions (visible...

  4. Baryogenesis via Asymmetric Evaporation of Primordial Black Holes

    hep-ph 2025-08 conditional novelty 6.0 of 10

    Evaporating primordial black holes, biased by a new gravitational interaction, can reproduce the observed baryon asymmetry once entropy dilution and chemical-potential-dependent emission are included.

  5. Gravitational wave signatures of primordial black hole accretion during early matter domination

    hep-ph 2025-05 conditional novelty 6.0 of 10

    PBHs that form in a radiation era and accrete during an early matter era could produce a two-peak GW background detectable by LISA or BBO for asteroid-mass PBHs as all of dark matter.

  6. Investigating a strong first-order electroweak phase transition in the RxSM at future linear $e^+e^-$ colliders and LISA

    hep-ph 2026-03 conditional novelty 5.5 of 10

    In the RxSM, singlet-driven SFOEWPTs yield strong LISA GW signals with SM-like Higgs couplings, while doublet-driven ones yield large κ_λ deviations visible at ILC1000 but weak GWs.

  7. PBH formation and Gravitational Waves as Multi-messenger Signals of First-order Phase Transitions

    hep-ph 2026-07 conditional novelty 5.0 of 10

    False-vacuum collapse during first-order phase transitions can form PBHs and emit GWs across a broad parameter range, and MeV-scale classically conformal U(1)_{B-L} symmetry breaking has the largest region where both ...
