Abstract

In this proceedings contribution I review recent progress concerning the suppression of bottomonium production in the quark-gluon plasma.  Making use of open quantum system methods applied to potential non-relativistic quantum chromodynamics one can show that the dynamics of heavy-quarkonium bound states satisfying the scale hierarchy 1/a0 » πT ∼ mD  » E obey a Lindblad equation whose solution provides the quantum evolution of the heavy-quarkonium reduced density matrix.  To solve the resulting Lindblad equation we use a quantum trajectories algorithm which allows one to include all possible angular momentum states of the quark-antiquark probe in a scalable manner.  We solve the Lindblad equation using a tuned 3+1D dissipative hydrodynamics code for the background temperature evolution.  We then consider a large number of Monte-Carlo sampled bottomonium trajectories embedded in this background.  This allows us to extract the centrality- and pT-dependence of the nuclear suppression factor RAA[Υ] and elliptic flow v2[Υ].  We find good agreement between our model predictions and available √ sNN = 5.02 TeV = 5.02 TeV Pb-Pb collision experimental data from the ALICE, ATLAS, and CMS collaborations.
