Description
We compute the shear viscosity of weakly coupled N=4 supersymmetric Yang-Mills theory. Our result for η/s, the viscosity to entropy-density ratio, is many times smaller than the corresponding weak-coupling result in QCD. This suggests that η/s of QCD near the transition point is several times larger than the viscosity bound, η/s≥1/4π
