Explaining Snowball-in-Hell Phenomena in Heavy-Ion Collisions Using a Novel Thermodynamic Variable

Author(s): Eric Braaten, Kevin Ingles, and Justin Pickett A loosely bound hadronic molecule produced by a relativistic heavy-ion collision has been described as a “snowball in hell” since it emerges from a hadron resonance gas whose temperature is orders of magnitude larger than the binding energy of the molecule. This remarkable phenomenon can be explaine… [Phys. Rev. Lett. 134, 252301] Published Thu Jun 26, 2025
