论文摘要
探索模型依赖性的程度，我们研究了某些ANSAETZE对QCD拓扑敏感性中校正项T依赖性的影响。 ETA'-ETA复合物在通常的isospin对称性限制中对t> 0产生不良影响的一种产生不良影响，在很大程度上可以从其独特的行为中治愈，并与另一个同意，当允许isospin对称性的破坏并采用逼真的夸克质量比率m_u/m_d/m_d = 0.50。
Exploring the extent of model dependence, we study effects of certain Ansaetze for the T-dependence of the correction term in the QCD topological susceptibility. The one producing unwanted effects on results at T > 0 in the eta'-eta complex in the usual limit of isospin symmetry, is largely cured from its peculiar behavior and brought into agreement with the other, when breaking of isospin symmetry is allowed and the realistic quark mass ratio m_u/m_d = 0.50 is adopted.
