摘要:
We estimate the coupling constants and decay widths of the SU(3) partners of the Omega(2012) 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 SU(3) analysis. We observe a good agreement between the predictions of both approaches. Moreover, our result on the decay width of Omega -> Xi K 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 SU(3) partners of the Omega(2012) baryon.
