While first order phase transitions (FOPTs) have been extensively studied as promising cosmological sources of gravitational waves, the phenomenon of particle production from the dynamics of the background field during FOPTs has received relatively little attention in the literature, where it has only been studied with semi-analytic estimates in some simplified settings. This paper provides improved numerical studies of this effect in more realistic frameworks, revealing important qualitative details that have been missed in the literature. We also provide easy to use analytic formulae that can be used to calculate particle production in generic FOPT setups.

  1. Particle production from bubble collisions

    hep-ph 2026-07 conditional novelty 8.0

    Heavy particles are produced in bubble-wall collisions by on-shell partonic scatterings, not by off-shell decay of the classical field, so the earlier rates and their phenomenological signals are parametrically overestimated.

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

    hep-ph 2026-07 conditional novelty 7.0

    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.

  3. Particle productions during collisions of highly boosted bubble walls

    hep-ph 2026-07 conditional novelty 7.0

    Bubble-wall collisions produce ultra-heavy particles with a universal spectrum ∝ [V'(2vφ)]²/χ⁴, localized at the collision instant.

  4. Cosmic Collider Gravitational Waves sourced by Right-handed Neutrino production from Bubbles: Testing Seesaw, Leptogenesis and Dark Matter

    astro-ph.CO 2026-01 unverdicted novelty 7.0

    Bubble collisions in a seesaw model produce right-handed neutrinos that source novel gravitational waves detectable by LISA, ET, and LVK while allowing the lightest RHN to explain dark matter or enable leptogenesis.

  5. Particle Production via Rippled Bubble Walls

    hep-ph 2026-07 conditional novelty 6.0

    A rippled bubble wall produces heavy particles resonantly when the momentum transfer matches the ripple frequency, potentially raising dark-matter abundance by orders of magnitude.

  6. A New Origin of the Big Bang from Dark-Sector-Induced Vacuum Decay and Its Gravitational-Wave Signal

    hep-ph 2026-06 unverdicted novelty 5.0

    A model in which inflaton energy goes exclusively to a dark sector, delaying SM thermalization until a false-vacuum decay produces a GW background with present-day Omega_GW up to 3e-8.

  7. Dark Matter Production from Bubble Collisions during a First-Order Phase Transition at the End of Inflation

    hep-ph 2026-05 unverdicted novelty 5.0

    Bubble collisions during a first-order phase transition at the end of inflation can generate the observed dark matter abundance in a restricted region of parameter space via direct production and spectator decays.

  8. Bounds from D/H on baryogenesis models

    hep-ph 2026-04 unverdicted novelty 2.0

    Deuterium-to-hydrogen measurements leave most electroweak baryogenesis parameter space unconstrained while imposing stronger exclusions on alternative baryogenesis models.
