Thomas Hilger, Carina Popovici, Maria Gomez-Rocha, Andreas Krassnigg

摘要:

在协变的Bethe-Salpeter方程方法中,我们利用QCD的彩虹梯截断模型,研究了有效相互作用的使用,目的是再现QCD现象。我们扩展了以前的研究,目前的结果为基础和激发介子状态的bottomonium和charmonium系统,其中的结果是令人惊讶的好,大多数国家。此外,我们还对奇异量子数态和光夸克域进行了讨论。

英文摘要:

In a covariant Bethe-Salpeter-equation approach and with a rainbow-ladder truncated model of QCD, we investigate the use of an effective interaction with the goal of reproducing QCD phenomenology. We extend previous studies and present results for ground and excited meson states in the bottomonium and charmonium systems, where the results are surprisingly good for most states. In addition, we formulate a critical outlook on states with exotic quantum numbers as well as the light-quark domain.
