We present potential non-relativistic quantum chromodynamics (pNRQCD)predictions for bottomonium suppression in sqrt(sNN) = 200 GeV, 2.76 TeV, and5.02 TeV heavy-ion collisions using an open quantum systems (OQS) descriptionof the reduced heavy-quark anti-quark density matrix. Compared to priorOQS+pNRQCD studies we include the rapidity dependence of bottomonium productionand evolution, allowing for a fully 3-dimensional description of bottomoniumtrajectories in the quark-gluon plasma. The underlying formalism used tocompute the ground and excited state survival probabilities is based on aLindblad equation that is accurate to next-to-leading order (NLO) in thebinding energy over temperature. For the background evolution, we make use of a3+1D viscous hydrodynamics code which reproduces soft hadron observables at allthree collision energies. We find good agreement between NLO OQS+pNRQCDpredictions and data taken at LHC energies, however, at RHIC energies, there istension with recent bottomonium suppression measurements by the STARcollaboration.
