Coupling constant dependence of the shear viscosity in N=4 supersymmetric Yang-Mills theory
Coupling constant dependence of the shear viscosity in N=4 supersymmetric Yang-Mills theory
Gauge theory–gravity duality predicts that the shear viscosity of N=4 supersymmetric SU(Nc) Yang–Mills plasma at temperature T in the limit of large Nc and large 't Hooft coupling is independent of the coupling and equals to . In this paper, we compute the leading correction to the shear viscosity in inverse powers of 't Hooft coupling using the ??-corrected low-energy effective action of type IIB string theory. We also find the correction to the ratio of shear viscosity to the volume entropy density (equal to 1/4? in the limit of infinite coupling). The correction to 1/4? scales as with a positive coefficient.

Abstract
Gauge theory–gravity duality predicts that the shear viscosity of N=4 supersymmetric SU(Nc) Yang–Mills plasma at temperature T in the limit of large Nc and large 't Hooft coupling is independent of the coupling and equals to . In this paper, we compute the leading correction to the shear viscosity in inverse powers of 't Hooft coupling using the ??-corrected low-energy effective action of type IIB string theory. We also find the correction to the ratio of shear viscosity to the volume entropy density (equal to 1/4? in the limit of infinite coupling). The correction to 1/4? scales as with a positive coefficient.
