Heavy quarkonia in a medium as a quantum dissipative system: Master-equation approach
The problem of the evolution of a heavy quarkonium in a medium can be recast
as that of a quantum dissipative system. Within the framework of the
master-equation approach to open quantum systems, we consider the real-time
dynamics of quarkonia. We find that in a plasma at fixed temperature, the
populations of the various quarkonium states evolve together, while their
momentum distribution satisfies a Fokker-Planck equation.Comment: 12 pages, 8 figures. Version 2 matches the published versio
