寻找大自然的礼物：强子回路和混合混合
Looking for a gift of Nature: Hadron loops and hybrid mixing
摘要：
我们研究了价q qbar与介子对的耦合如何改变传统q qbar和混合介子的性质。在对称极限下，具有相同J^PC的混合电路和传统q qbar之间的混合被证明是消失的。由于介子环的味道重和轻qqbar之间的混合被证明是双重的胶子介导的pQCD的结果，并从性质上不同的混合涉及光味单独。讨论了OZI规则对常规q-qbar介子和混合介子的有效性。
英文摘要：
We investigate how coupling of valence q qbar to meson pairs can modify the properties of conventional q qbar and hybrid mesons. In a symmetry limit the mixing between hybrids and conventional q qbar with the same J^PC is shown to vanish. Flavor mixing between heavy and light q qbar due to meson loops is shown to be dual to the results of gluon mediated pQCD, and qualitatively different from mixing involving light flavors alone. The validity of the OZI rule for conventional q qbar and hybrid mesons is discussed.
