标题： Effective field theory approach to N=4 supersymmetric Yang-Mills at finite temperature

摘要： 我们研究了在大N极限下，以't Hooft耦合常数\(g^2 N\)的幂次展开的\(N=4\)超对称\(SU(N)\)杨-米尔斯理论在有限温度下的自由能摄动展开。红外发散通过构建两个三维有效场论的层次结构来控制。这一过程被应用于计算自由能达到\((g^2 N)^\{3/2\}\)阶的修正，但它可以扩展到更高阶的修正。 显示英文摘要

摘要： We study the perturbation expansion of the free energy of N=4 supersymmetric SU(N) Yang-Mills at finite temperature in powers of 't Hooft's coupling g^2 N in the large N limit. Infrared divergences are controlled by constructing a hierarchy of two 3 dimensional effective field theories. This procedure is applied to the calculation of the free energy to order (g^2 N)^(3/2), but it can be extended to higher order corrections.
