Bubbletrons: Ultrahigh-Energy Particle Collisions and Heavy Dark Matter at Phase Transitions
Iason Baldes, Maximilian Dichtl, Yann Gouttenoire +1
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 cosmologi…

Particle shells from relativistic bubble walls
Iason Baldes, Maximilian Dichtl, Yann Gouttenoire +1
Relativistic bubble walls from cosmological phase transitions (PT) necessarily accumulate expanding shells of particles. We systematically characterize shell properties, and identi…
