Quarkonium Suppression in a Strongly-Coupled Quark–Gluon Plasma

We compute the quarkonium nuclear modification factor in a strongly coupled quark–gluon plasma for quarkonia that are S-wave Coulombic bound states. We perform the analysis in a non-relativistic effective field theory framework that is accurate at leading-order in the heavy-quark density expansion and at next-to-leading order in the multipole expansion. We write and solve the Lindblad equation for the heavy quark–antiquark density. Thermal mass shift, width and the Lindblad equation depend on only two non-perturbative parameters: the heavy-quark momentum diffusion coefficient and its dispersive counterpart. Finally, we provide preliminary numerical results for the nuclear modification factors of the 1S and 2S bottomonium states.
