Measurement of branching fractions of decays to Σ

By analyzing $\textit{e}$ $\textit{e}$ collision data taken at center-of-mass energies between 4.600 and 4.699 GeV with the BESIII detector at the BEPCII collider, corresponding to an integrated luminosity of 4.5 fb , we study the hadronic decays and using the single-tag method. The branching fraction ratio of relative to is determined to be 0.305 $\textit{±}$ 0.046 $\textit{±}$ 0.007 , and that of relative to is 0.336 $\textit{±}$ 0.094 $\textit{±}$ 0.037 . The ratio of is determined to be 1.73 $\textit{±}$ 0.22 $\textit{±}$ 0.16 . These results enrich our knowledge of charmed baryon decays.
