论文摘要
在这项工作中，我们显示了逐步计算的逐步计算，以量化带有二面体对称性的三环订单图对SU（2）热阳米尔斯理论中压力的辐射校正的贡献。我们调查了过去的发展，并对单独的通道组合进行了计算，该计算由Mandelstam变量定义，这些变量受两个4个换核个性的约束。发现了用于高温条件的分析整合近似值，以验证校正与此图的相关性。对蒙特卡洛方法进行了数值分析，以检查这种近似的有效性，以将其与完整的积分进行比较。为了控制所找到的温度依赖性，必须对所有二面环订单进行Dyson-Schwinger重新召集。
In this work we show the step by step calculations needed to quantify the contribution of a three-loop order diagram with dihedral symmetry to the radiative corrections of the pressure in SU(2) thermal Yang-Mills theory in deconfining phase. We surveyed past developments, and performed computations for separate channel combinations, defined by Mandelstam variables which are constrained by two 4-vertices. An analytically integrable approximation for high-temperature conditions was found, to verify the relevance of the corrections for this diagram. A numerical analysis with Monte Carlo methods was carried out to check the validity of such approximation, to compare it with the full integral. A Dyson-Schwinger resummation had to be performed to all dihedral loop orders in order to control the temperature dependency found.
