论文摘要
由我们较早的QCD拓扑敏感性依赖性对当前夸克质量和相应冷凝水的产物的敏感夸克味的依赖性的发现，我们允许破坏Isospin对称性。为了将U_A（1）对称性破坏和恢复的未来研究，我们（在t = 0）对低能量QCD的现象学上成功有效模型的夸克 - 质量参数进行了改装。它属于Dyson-Schinginger方法中的可分离性相互作用模型，用于媒体的媒介物 - 静脉标记子结构。
Motivated by our earlier findings of sensitive quark-flavor dependence of QCD topological susceptibility on products of current quark masses and corresponding condensates, we allow the breaking of isospin symmetry. For the purpose of future investigations of U_A(1) symmetry breaking and restoration at T > 0, we perform (at T = 0) refitting of the quark-mass parameters of a phenomenologically successful effective model of low-energy QCD. It belongs to the class of separable-interaction models within the Dyson-Schwinger approach to the quark-antiquark substructure of mesons.
