  The shear viscosity of quark gluon plasma is customarily estimated in the
literature using kinetic theory, which, however, is well known to break down
for dense interacting systems. Here we propose an alternative theoretical
approach based on recent advances in the physics of dense interacting
liquid-like systems, which is valid for strongly-interacting and arbitrarily
dense relativistic systems. With this approach, the viscosity of strongly
interacting dense heavy-quarks plasma is evaluated analytically, at the level
of special relativity. For QGP well above the confinement temperature, the
theory predicts that the viscosity increases with the cube of temperature, in
agreement with evidence.
