abstract
We consider the dissociation of heavy quarkonium in a medium close to thermal equilibrium but with a small momentum space anisotropy. Dissociation is defined to take place when the width of the ground state equals its binding energy. We show that if the anisotropic medium is obtained isentropically from the equilibrium one, then to first order in the anisotropy parameter the dissociation temperature remains unchanged. If, in contrast, the non-equilibrium system has a smaller entropy density than the equilibrium one, then the dissociation temperature increases with respect to the isotropic case, by up to 10% for modest anisotropies.

Imaginary potential and thermal width in the spinning black hole background from holography
In the planar limit of the Myers-Perry black hole, increasing the boost parameter makes the imaginary quarkonium potential appear at smaller separations and enlarges the thermal width, most strongly for transverse pair orientation.
