论文摘要

我们调查了$ s $ su(3)$ floation $ \ mathbf {6} _f $的$ p $ - 波底重男,并系统地研究了他们的$ d $ - 波腐烂到地面底部底部巴里子和伪斯卡利亚式膜中。与[PRD91,054034(2015)一起; PRD92,114007(2015); PRD95,094008(2017); EPJC80,80(2020)],使用QCD总规则和轻率总和规则在重夸克有效理论的框架内,对$ p $ - 波底底重的质谱和衰减特性进行了一项相当完整的研究。在所有可能性中,我们发现四个$σ_b$,四个$ξ^\ prime_b $和六个$ω_b$ baryons,宽度有限,并且能够观察到。他们的质量,相同多重组中的质量分裂以及提取衰减特性(在表V中进行了总结),以进行将来的实验搜索。

We investigate $P$-wave bottom baryons of the $SU(3)$ flavor $\mathbf{6}_F$, and systematically study their $D$-wave decays into ground-state bottom baryons and pseudoscalar mesons. Together with [PRD91, 054034 (2015); PRD92, 114007 (2015); PRD95, 094008 (2017); EPJC80, 80 (2020)], a rather complete study is performed on both mass spectra and decay properties of $P$-wave bottom baryons, using the method of QCD sum rules and light-cone sum rules within the framework of heavy quark effective theory. Among all the possibilities, we find four $Σ_b$, four $Ξ^\prime_b$, and six $Ω_b$ baryons, with limited widths and so capable of being observed. Their masses, mass splittings within the same multiplets, and decay properties are extracted (summarized in Table V) for future experimental searchings.
