在Dyson-Schwinger方程的框架下，我们讨论了以手性化学势μ5为附加尺度的QCD的手性相变。我们特别关注与被广泛接受的以及有趣的关键终点(CEP)相关的问题。在标量极化率的帮助下，我们发现在T-μ5面上可能没有CEP5，而在50 MeV时，T-μ5面上的相变可能完全交叉，这与晶格μ计算有明显的一致性。我们的研究也可能为其他一些与μ5相关的研究提供一些有用的提示。
Within the framework of Dyson-Schwinger equations , we discuss the chiral phase transition of QCD with a chiral chemical potential μ 5 as an additional scale. We focus especially on the issues related to the widely accepted as well as interesting critical end point (CEP). With the help of a scalar susceptibility, we find that there might be no CEP 5 in the T - μ 5 plane, and the phase transition in the T - μ 5 plane might be totally crossover when μ 50 MeV , which has apparent consistency with the lattice QCD calculation. Our study may also provide some useful hints to some other studies related to μ 5 .
