摘要

我们使用光锥和规则方法中的八重子分布振幅来估算 BELLE 协作发现的超子伙伴的耦合常数和衰变宽度。我们的研究包括将获得的相关衰变宽度结果与在味道分析框架内得出的结果进行比较。我们发现这两种方法的预测结果非常一致。此外，在模型预测的不确定性范围内，我们关于衰变宽度的结果与现有的实验结果是一致的。这些结果可以为确定重子伙伴的性质提供有益的启示。

Analysis of strong decays of SU(3) partners of Ω(2012) baryon

We estimate the coupling constants and decay widths of the partners of the hyperon, as discovered by the BELLE Collaboration, using the distribution amplitudes of the octet baryons within the light cone sum rules method. Our study includes a comparison of the obtained results for the relevant decay widths with those derived within the framework of the flavor analysis. We observe a good agreement between the predictions of both approaches. Moreover, our result on the decay width of is compatible with the existing experimental result within the uncertainties of the model predictions. These results can provide helpful insights for determining the nature of the partners of the baryon.
