论文摘要
在有限温度下,可以通过$λ^{5/2} $来计算$ {\ cal n} = 4 $ supersymmetric yang-mills的自由能密度。有效的现场理论方法提供了一种有用的替代方法来简化这些计算。在此程序的贡献中,我回顾了与我的合作者的最新工作,我们使用有效的现场理论方法来计算$ {\ cal n} = 4 $ supersymmetricric yang-mills在四个时空维度通过第二阶的超级对称的Yang-mills,'t Hooft t Hooft tohing $λ$。在此订单下,对自由能密度的贡献来自硬尺度$ t $和软尺度$ \sqrtλt$。从尺寸减小获得的有效拉格朗日式中的系数和量表$ gt $的效果可以使用有效理论中的扰动方法计算,从尺度$ t $中的贡献进行了。
At finite temperature the free energy density of ${\cal N}=4$ supersymmetric Yang-Mills can be calculated using resummed perturbation theory through the order $λ^{5/2}$. Effective field theory methods provide a useful alternative approach to streamline these calculations. In this proceedings contribution, I review recent work with my collaborators where we used effective field theory methods to calculate the free energy density of ${\cal N}=4$ supersymmetric Yang-Mills in four spacetime dimensions through second order in the 't Hooft coupling $λ$. At this order the contributions to the free energy density come from the hard scale $T$ and the soft scale $\sqrtλT$. The contribution from the scale $T$ enters through the coefficients in the effective Lagrangian obtained by dimensional reduction and the effects of the scale $gT$ can be calculated using perturbative methods in the effective theory.
