“…In this letter, we propose a novel dynamical approach starting with physical parameters that allow us to compute the wall velocity and find the fluid profiles. Our description is easily applied to non-equilibrium cases [85][86][87][88]. We model the wall as a phase boundary with energy conservation determining whether particles will penetrate the wall or be reflected.…”

We present a new approach to studies of bubble dynamics in fluids. Relying on particle-based simulations, this method is general and suitable for cases where the commonly used perfect fluid description fails. We study expanding true vacuum bubbles surrounded by free or self-interacting particles and quantify how self-interactions affect the terminal bubble wall velocity. We find that, for sufficiently strongly self-interacting fluids, local thermal equilibrium is maintained around the bubble wall and the fluid profile is similar to that obtained with the perfect fluid description.

“…It has been known that the strongly first-order EWPT predicts the gravitational waves (GWs) in the frequency range of 10 −3 -10 −1 Hz [13], which could be measured at the future GW interferometers like LISA [14] and DECIGO [15]. Furthermore, it has been pointed out that some types of the first-order phase transition could produce JHEP06(2022)027 primordial black holes (PBHs) [16][17][18][19][20][21][22][23]. The prediction of the PBHs produced by the strongly first-order EWPT has been recently studied in refs.…”

We investigate the strongly first-order electroweak phase transition using an effective field theoretical approach. The standard effective field theory with finite number truncation of higher dimensional operators fails in the typical parameter space where the strongly first-order phase transition is realized because it cannot describe the non-decoupling quantum effect of new physics beyond the standard model. To parameterize the non-decoupling quantum effect, we employ the nearly aligned Higgs effective theory in which the Higgs potential is parameterized by a Coleman-Weinberg like form. Extending this framework with finite temperature corrections, we study the parameter space for realizing the strongly first-order phase transition, and estimate the gravitational wave produced at the phase transition.

“…One of such mechanisms is strongly first-order phase transition in the early Universe [26,27]. Recently, there are several works discussing new mechanisms of PBH production from first-order phase transition in the early universe [28][29][30][31][32]. In these works, the authors are mainly interested in explaining the possibility that PBHs play a role of dark matter.…”

Primordial black holes can be produced by density fluctuations generated from delayed vacuum decays of first-order phase transition. The primordial black holes generated at the electroweak phase transition have masses of about 10 −5 solar mass. Such primordial black holes in the mass range can be tested by current and future microlensing observations, such as Subaru HSC, OGLE, PRIME and Roman telescope. Therefore, we may be able to explore new physics models with strongly first-order electroweak phase transition via primordial black holes. We examine this possibility by using models with first-order electroweak phase transition in the standard model effective field theory with dimension 6 and 8 operators. We find that depending on parameters of the phase transition a sufficient number of primordial black holes can be produced to be observed by above mentioned experiments. Our results would suggest that primordial black holes can be used as a new probe of models with strongly first-order electroweak phase transition, which has complementarity with measurements of the triple Higgs boson coupling at future collider experiments and observations of gravitational waves at future space-based interferometers.
