Upsilon suppression in the Schrödinger-Langevin approach

Abstract

We treat the question of bottomonia suppression in ultrarelativistic heavy ion collisions (URHIC) as a dynamical open quantum problem, tackled for the first time using the Schrödinger-Langevin equation. Coupling this equation to the EPOS2 event generator, predictions are made for the nuclear modification factor of ${\rm Y}(1S)$ and ${\rm Y}(2S)$.
