用$J^{PC}=2^{--}$研究无味轻介子

Study of Unflavored Light Mesons with $J^{PC}=2^{--}$

Dan Guo, Cheng-Qun Pang, Zhan-Wei Liu, Xiang Liu

摘要:

通过研究谱和Okubo-Zweig-Iizuka规则所允许的二体强衰变,系统地研究了无味轻介子族$ω_2$,$ρ_2$和$ϕ_2$.包括实验观察到的四个态和其他预言的态,部分衰变宽度的唯象分析可以验证这些态到族中的相应分配。此外,我们还提供了主要衰变通道的典型分支比,特别是缺失的基态,这有助于在实验中寻找或确认它们,探索这些族的更多性质。

英文摘要:

The unflavored light meson families, namely $ω_2$, $ρ_2$, and $ϕ_2$, are studied systematically by investigating the spectrum and the two-body strong decays allowed by Okubo-Zweig-Iizuka rule. Including the four experimentally observed states and other predicted states, phenomenological analysis of the partial decay widths can verify the corresponding assignments of these states into the families. Moreover, we provide typical branching ratios of the dominant decay channels, especially for missing ground states, which is helpful to search for or confirm them and explore more properties of these families at experiment.
