On the assignment of1~2H_6meson nonet
关于1~3H_6介子九重态的填充
Based on the mass relation obtained in the framework of meson-meson mixing, with the help of the assumption that for the almost ideally mixing meson nonets, the corrections deduced by the flavor-dependent quarkonia tranistion can be ignored, and the mass of the isodoublet of the 2~3S_1 meson nonet is predicted to be 1584 ( 16.
借助对于接近理想混合的介子九重态,味道有关的夸克偶素间的湮灭效应可以忽略这样一个假定,利用在介子、介子混合框架下导出的质量关系,预言23S1介子九重态中同位旋二重态的质量大约为1584±16。

In the framework of the meson-meson mixing and the nonrelativistic constituent quark model, it is found that the K(~3P_1) - K(~P_1) mixing angle is about±59°.
在介子-介子混合以及非相对论组分夸克模型两种不同的理论框架下，我们唯象研究了K(~3P_1)和K(~1P_1)的混合，发现它们的混合角大约为±59°，进一步，我们在~3P_0介子衰变模型下给出了K_1(1270)和K_1(1400)的强子衰变宽度，同时我们也给出了关于这两个物理态在τ衰变中的产生比率，对比我们的理论预言和可得到的关于K_1(1270)和K_1(1400)的实验信息显示，目前的实验信息支持K(~3P_1)和K(~1P_1))的混合角为+59°。
