论文摘要
我们在高温阶段$ n_f = 2+1 $ 1 $ lattice QCD中研究$ u（1）_a $异常。量规集合是用Möbius域壁（MDW）fermions生成的，在测量结果中，确定因子已重新持续到重叠费用。我们报告了重叠dirac频谱，$ u（1）_a $敏感性以及拓扑敏感性的结果，$ t = 204 $和$ 175 $ MEV。
We study the $U(1)_A$ anomaly in the high-temperature phase of $N_f=2+1$ lattice QCD with chiral fermions. Gauge ensembles are generated with Möbius domain-wall (MDW) fermions, and in the measurements the determinant is reweighted to that of overlap fermions. We report the results for the overlap Dirac spectrum, $U(1)_A$ susceptibility, and topological susceptibility at $T=204$ and $175$ MeV.
