Has the QCD critical point been signaled by observations at the BNL relativistic heavy ion collider?

The shear viscosity to entropy ratio (eta/s) is estimated for the hot and dense QCD matter created in Au+Au collisions at BNL Relativistic Heavy Ion Collider (root(s(NN)) =200 GeV). A very low value is found; eta/s similar to 0.1, which is close to the conjectured lower bound (1/4 pi). It is argued that such a low value is indicative of thermodynamic trajectories for the decaying matter which lie close to the QCD critical end point.
