论文摘要
我们提出了有关欧几里得拓扑电荷密度相关函数的研究的第一个结果。为了获得明确定义的拓扑电荷密度并提高相关函数的信号,我们使用梯度流。我们研究了对精细淬灭晶格的流动时间依赖性。这项研究的最终目标是对纯SU(3)等离子体进行连续外推,并提取相关的传输系数SPHALERON速率。
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.
