Description

We will present first results of our study of the Euclidean topological charge density correlator.
In order to get a well defined topological charge density and to improve the signal of the correlators at large distances we make use of the gradient flow.
We investigate the flow-time dependence on large and fine quenched lattices and compare to results of 2+1-flavor HISQ lattices. The final goal of this study is to perform a continuum extrapolation for the pure SU(3) plasma, the relevance of the results to full QCD and to extract the related transport coefficient, the sphaleron rate.
