| Description: | By analyzing e+e− collision data taken at center-of-mass energies s between 4.600 and 4.699 GeV with the BESIII detector at the BEPCII collider, corresponding to an integrated luminosity of 4.5 fb−1, we study the hadronic decays Λc+→Σ+η and Λc+→Σ+η′ using the single-tag method. The branching fraction ratio of Λc+→Σ+η relative to Λc+→Σ+π0 is determined to be 0.305 ± 0.046stat.± 0.007syst., and that of Λc+→Σ+η′ relative to Λc+→Σ+ω is 0.336 ± 0.094stat± 0.037syst. The ratio of BΛc+→Σ+η′BΛc+→Σ+η is determined to be 1.73 ± 0.22stat.± 0.16syst. |
