通过重新称重，纯胶QCD中的$χ_{\textrm{top}}(T \gg T_{\textrm{c}})$
$χ_{\textrm{top}}(T \gg T_{\textrm{c}})$ in pure-glue QCD through reweighting
摘要：
我们用SU（3）纯Yang-Mills理论计算了2.5Tc和4.1Tc的拓扑磁化率。我们定义拓扑的帮助下，梯度流，我们在很大程度上克服了这个问题的统计数据不佳，在高温下，通过应用一个重新加权技术的拓扑电荷，测量后，一个特定的少量的梯度流。这使我们能够获得一个配置的样本，比较拓扑扇区具有良好的统计数据，增强了拓扑之间的隧道。我们引用连续外推的结果在这两个温度下，并得出结论，我们的方法是可行的，可以扩展到完全的QCD与费米子的情况下，没有新的概念问题。
英文摘要：
We calculate the topological susceptibility at 2.5 Tc and 4.1 Tc in SU(3) pure Yang-Mills theory. We define topology with the help of gradient flow and we largely overcome the problem of poor statistics at high temperatures by applying a reweighting technique in terms of the topological charge, measured after a specific small amount of gradient flow. This allows us to obtain a sample of configurations which compares topological sectors with good statistics, with enhanced tunneling between topologies. We quote continuum extrapolated results at these two temperatures and conclude that our method is viable and can be extended without new conceptual problems to the case of full QCD with fermions.
