dc.description.abstract | We address the evolution of heavy-quarkonium states in an expanding quark-gluon plasma by
implementing effective field theory techniques in the framework of open quantum systems. In this
setting we compute the nuclear modification factors for quarkonia that are S-wave Coulombic bound states
in a strongly coupled quark-gluon plasma. The calculation is performed at an accuracy that is leading order
in the heavy-quark density expansion and next-to-leading order in the multipole expansion. The
quarkonium density-matrix evolution equations can be written in the Lindblad form, and, hence, they
account for both dissociation and recombination. Thermal mass shifts, thermal widths and the Lindblad
equation itself depend on only two nonperturbative parameters: the heavy-quark momentum diffusion
coefficient and its dispersive counterpart. Finally, by numerically solving the Lindblad equation, we
provide results for the ϒð1SÞ and ϒð2SÞ suppression. | |
