Description

We study bottomonium evolution in QGP using an open quantum systems approach. Previous works [1,2] study quarkonia using Lindblad equation in Brownian regime i.e, at zero frequency limit of the medium correlators. Finite frequency effects of the medium are important [3,4] for quarkonia dynamics when the binding energy is of the order of temperature (beyond the Brownian regime). We include these effects in a non-Markovian master equation and numerically solve it with a hydro background to calculate suppression at CMS and RHIC energies.
