Description

Quarkonium production in ultrarelativistic heavy ions collisions is one of the best probes of the QGP formed in these collisions. Resorting to acurate methods to describe the $Q\bar Q$ evolution in a QGP is a prerequisite for the precise interpretation of experimental data. Following [1], we present exact numerical solutions in a 1D setting of quantum master equations (QME) derived in [2]. Distinctive features of the $Q\bar Q$ evolution with the QME are presented; phenomenological consequences are addressed by considering evolutions in EPOS4 temperature profiles. Next, we investigate the accuracy of the semiclassical approximation (often used to to describe charmonium production in URHIC, e.g. [1,3]) by benchmarking the corresponding evolutions on the exact solutions derived with the QME for the case of a $c\bar c$ pair.
