Particle production from bubble collisions
Anish Ghoshal, Pratyay Pal, Alessandro Strumia
The paper investigates how ultra‑relativistic bubble collisions during cosmological phase transitions can generate very heavy particles, introducing a partonic‑like formalism based…

Cosmic Collider Gravitational Waves sourced by Right-handed Neutrino production from Bubbles: Testing Seesaw, Leptogenesis and Dark Matter
Anish Ghoshal, Pratyay Pal
We study a minimal type-I seesaw framework in which a first-order phase transition (FOPT), driven by a singlet scalar, produces right-handed neutrinos (RHNs) through bubble collisi…
