当应用最大熵方法 (MEM) 分析 QCD 中的强子相关函数时,一个中心问题是了解该方法可以在多大程度上区分束缚态、共振和连续谱对谱函数的贡献。我们通过分析零温度下的介子和双夸克相关函数以及自由夸克反夸克相关器来讨论这些问题。后者测试了MEM在高温QCD上的适用性。
When applying the maximum entropy method (MEM) to the analysis of hadron correlation functions in QCD a central issue is to understand to what extent this method can distinguish bound states, resonances and continuum contributions to spectral functions. We discuss these issues by analyzing meson and diquark correlation functions at zero temperature as well as free quark anti-quark correlators. The latter test the applicability of MEM to high temperature QCD.
