Cosmic Colliders: High Energy Physics with First-Order Phase Transitions
Bibhushan Shakya
Collisions of vacuum bubbles in the early Universe can act as cosmic-scale high-energy colliders with energy reach close to the Planck scale. Such "cosmic colliders" would represen…
Gravitational Waves from Particles Produced from Bubble Collisions in First-Order Phase Transitions
Keisuke Inomata, Marc Kamionkowski, Kentaro Kasai +1
We discuss a new source of gravitational waves (GWs) from first-order phase transitions. The collisions of bubbles of the new phase can efficiently produce particles that couple to…
Leptogenesis via Bubble Collisions
Martina Cataldi, Bibhushan Shakya
We present a novel realization of leptogenesis from the decays of sterile (right-handed) neutrinos (RHNs) produced from runaway bubble collisions at a first order phase transition.…
Nonthermal Heavy Dark Matter from a First-Order Phase Transition
Gian F. Giudice, Hyun Min Lee, Alex Pomarol +1
We study nonthermal production of heavy dark matter from the dynamics of the background scalar field during a first-order phase transition, predominantly from bubble collisions. In…
