| contents | We initiate the study of `bubbletrons', by which we mean ultra-high-energy collisions of the particle shells that generically form at the walls of relativistic bubbles in cosmological first-order phase transitions (PT). As an application, we calculate the maximal dark matter mass $M_{DM}$ that bubbletrons can produce in a $U(1)$ gauge PT, finding $M_{DM} \sim 10^5/10^{11}/10^{15}$ GeV for PT scales $v_ϕ\sim 10^{-2}/10^3/10^9$ GeV. Bubbletrons realise a novel link between ultra-high-energy phenomena and gravitational waves (GW) sourced at the PT, from nanohertz to megahertz frequencies. |
