论文摘要
由强相互作用界定的重型巴属系统具有丰富的内部结构，因此其质谱可以具有与电磁相互作用界定的原子线光谱相似的精细结构。我们系统地研究$ p $ - 波$ω_b$ baryons的内部结构，并计算其$ d $ - 波衰减属性。本研究以及我们先前关于其质谱的研究和$ s $ - 波衰减的属性，表明LHCB最近发现的所有四个激动的$ω_b$ baryons可以很好地解释为$ p $ -wave $ - 波$ω_b$ baryons，它们美丽的精美结构与$ p $ p $ $ wave $ baryons的丰富内部结构直接相关。
The heavy baryon system bounded by the strong interaction has a rich internal structure, so its mass spectra can have the fine structure similar to the line spectra of atom bounded by the electromagnetic interaction. We systematically study the internal structure of $P$-wave $Ω_b$ baryons and calculate their $D$-wave decay properties. The present study, together with our previous studies on their mass spectra and $S$-wave decay properties, suggest that all the four excited $Ω_b$ baryons recently discovered by LHCb can be well explained as $P$-wave $Ω_b$ baryons, and their beautiful fine structure is directly related to the rich internal structure of $P$-wave $Ω_b$ baryons.
