论文摘要
晶格测量提供了足够的信息，以固定欧几里得时间中的长距离有效场理论的参数。使用这样的理论，我们检查了从欧几里得到Minkowski时空的有限温度下复合算子在有限温度下的长距离相关函数的分析延续。我们通过一个明确的计算表明，Pion相关函数的分析延续是可能的，并引起非平凡效应。其中的可能性是，在欧几里得相关因子的晶格计算的支持下，即使在高于QCD交叉高于温度的温度下，也可以通过（非常巨大的）旋转来理解长距离激发。
Lattice measurements provide adequate information to fix the parameters of long distance effective field theories in Euclidean time. Using such a theory, we examine the analytic continuation of long distance correlation functions of composite operators at finite temperature from Euclidean to Minkowski space time. We show through an explicit computation that the analytic continuation of the pion correlation function is possible and gives rise to non-trivial effects. Among them is the possibility, supported by lattice computations of Euclidean correlators, that long distance excitations can be understood in terms of (very massive) pions even at temperatures higher than the QCD cross over temperature.
