报告摘要：

I will present a connection between the open quantum system formalism and the transport equation for quarkonium inside quark-gluon plasma. I will show that under the weak coupling and Markovian approximations, the evolution equation of the open system, the Lindblad equation, turns to a Boltzmann transport equation after a Wigner transform is applied to the system density matrix. I will demonstrate how the separation of physical scales justifies the approximations, by using effective field theory of QCD. Finally, by coupling the transport equations of quarkonia and open heavy flavors, I will study how the system of open and hidden heavy flavors reaches thermal equilibrium inside a quark-gluon plasma box. Phenomenological results on quarkonium production will also be presented.
