Quarkonium in a non-ideal hot QCD Plasma

Understand

Substantial anisotropies should occur in the hot expanding QCD plasma produced in relativistic heavy-ion collisions due to non-vanishing shear viscosity.

• We discuss the form of the real-time, hard thermal loop resummed propagator for static gluons in the presence of such anisotropies and the consequences for quarkonium binding.
• It has been predicted that the propagator develops an imaginary part due to Landau damping at high temperature.
• This generates a much larger width of quarkonium states than the Appelquist-Politzer vacuum estimate corresponding to decay into three gluons.
