我们考虑了用AdS/CFT对应对强耦合非阿贝尔等离子体剪切粘度与熵密度之比的修正。特别地，高导数项与五形式雷蒙-雷蒙通量，已被忽略在所有以前的计算，包括在内。这提供了第一个可靠的计算，在逆t霍夫特耦合中，对著名的结果{eta}/s=1/4{pi}的阶改正。计算颜色数的反比幂的前导校正。我们的结果非常普遍地适用于全息对偶中具有内流形L{sub pqr}的颤振规范理论。我们的分析表明，任何热学性质，例如，这些理论中的所有流体力学量，都不会受到这一阶的五形式通量项的影响。
We consider corrections to the ratio of the shear viscosity to the entropy density in strongly coupled non-Abelian plasmas using the AdS/CFT correspondence. In particular, higher-derivative terms with the five-form Ramond-Ramond flux, which have been ignored in all previous calculations, are included. This provides the first reliable calculation of the leading order correction in the inverse 't Hooft coupling to the celebrated result {eta}/s=1/4{pi}. The leading correction in inverse powers of the number of colors is computed. Our results hold very generally for quiver gauge theories with an internal manifold L{sub pqr} in the holographic dual. Our analysis implies that any thermal properties, e.g., all hydrodynamic quantities in these theories, will not be affected by the five-form flux terms at this order.
