摘要

我们提出了欧几里得拓扑电荷密度相关函数的初步研究结果。为了得到一个定义良好的拓扑电荷密度，并在大间距处改善相关函数的信号，我们利用了梯度流。我们研究了流动时间与精细淬火晶格的关系。本研究的最终目标是对纯SU(3)等离子体进行连续统外推，并提取相关的输运系数，即闪散子速率。

Euclidean correlation functions of the topological charge density

We present first results of our study on the Euclidean topological charge density correlation function. In order to get a well defined topological charge density and to improve the signal of the correlation function at large separations we make use of the gradient flow. We investigate the flow-time dependence on fine quenched lattices. The final goal of this study is to perform a continuum extrapolation for the pure SU(3) plasma and to extract the related transport coefficient, the sphaleron rate.
