Bottomonium suppression in the quark-gluon plasma -- From effective field theories to non-unitary quantum evolution
Abstract
In this proceedings contribution I review recent work which computes the suppression of bottomonium production in heavy-ion collisions using open quantum systems methods applied within the potential non-relativistic quantum chromodynamics (pNRQCD) effective field theory. I discuss how the computation of bottomonium suppression can be reduced to solving a Gorini-Kossakowski-Sudarshan-Lindblad (GKSL) quantum master equation for the evolution of the b-bbar reduced density matrix. The open quantum systems approach used allows one to take into account the non-equilibrium dynamics and decoherence of bottomonium in the quark-gluon plasma. Finally, I present comparisons of phenomenological predictions obtained using a recently obtained next-to-leading-order GKSL equation with ALICE, ATLAS, and CMS experimental data for bottomonium suppression and elliptic flow.
