Measurement of the cross sections of e+e-→ KS0Ξ̅0Λ/Σ0 + c.c. at center-of-mass energies between 3.510 and 4.951 GeV
Abstract
Using e+e- collision data samples collected with the BESIII detector at the BEPCII at center-of-mass energies between 3.510 and 4.951 GeV corresponding to an integrated luminosity of 44.55 fb−1, the Born cross sections of the processes e+e- → KS0 Ξ̅0 Λ/Σ0+c.c. are measured with a partial-reconstruction strategy. The dressed cross sections for the channels e+e- → KS0 Ξ̅0 Λ/Σ0 + c.c. are fitted with a model consisting of a power-law function and a charmonium (-like) resonance, considering the candidates ψ(3770), ψ(4040), ψ(4160), Y(4230), Y(4360), ψ(4415), Y(4500), Y(4660), and Y(4710). No significant resonance contribution is observed in any of the fits. The upper limits for the products of the electronic partial widths and branching fractions at the 90% confidence level are provided.
