标题： Mixing and $m_q$ dependence of axial vector mesons in the Coulomb gauge QCD model

摘要： 我们讨论来自北卡罗来纳州立大学的库仑规范QCD模型的Tamm-Dancoff近似中的纯$q\bar{q}$轴矢量介子。 虽然最近的研究强调了开放介子-介子通道的配置混合，但我们此处集中于更简单的闭合通道问题，并通过广泛的夸克质量范围跟踪$1^+$混合。 我们还检查了它们的径向激发，并与它们讨论对手征对称性破缺不敏感的概念。 显示英文摘要

摘要： We discuss pure $q\bar{q}$ axial-vector mesons in the Tamm-Dancoff approximation of the Coulomb-gauge QCD model from NCSU. While recent studies have put emphasis in configuration mixing with open meson-meson channels, we here concentrate on the simpler closed-channel problem and follow the $1^+$ mixing through a wide range of quark masses. We also examine their radial excitations and discuss with them the concept of insensitivity to chiral symmetry breaking.
