Ω^0_c重子是一种独特的粲六重态重子，通过弱相互作用衰变。本工作研究SU(3)_F极限下Ω^0_c衰变的拓扑振幅，完整给出对Ω^0_c衰变为十重态和八重态重子有贡献的树图和企鹅诱导图；通过张量分析推导拓扑振幅与SU(3)不可约振幅的线性关系，得到若干同位旋关系，还推导了用于检验Körner-Pati-Woo定理的相关关系。
英文摘要
The $Ω^0_c$ baryon is unique among charmed sextet baryons because it decays through the weak interaction. In this work, we investigate the topological amplitudes of $Ω_c^0$ decays in the $SU(3)_F$ limit. The complete set of tree- and penguin-induced diagrams contributing to $Ω_c^0$ decays into decuplet and octet baryons is presented. The linear relations between the topological amplitudes and the $SU(3)$ irreducible amplitudes are derived through tensor analysis. Several isospin relations are obtained, and additional relations are derived to test the Körner-Pati-Woo theorem.
