abstract = "Using the entire data sample of 980 fb-1 collected with the Belle detector at the KEKB asymmetric-energy e+e- collider, we present measurements of the branching fractions of the Cabibbo-favored decays Ξc0→ΛKS0, Ξc0→Σ0KS0, and Ξc0→Σ+K-. Taking the decay Ξc0→Ξ-π+ as the normalization mode, we measure the branching fraction ratio B(Ξc0→ΛKS0)/B(Ξc0→Ξ-π+)=0.229±0.008±0.012 with improved precision, and measure the branching fraction ratios B(Ξc0→Σ0KS0)/B(Ξc0→Ξ-π+)=0.038±0.006±0.004 and B(Ξc0→Σ+K-)/B(Ξc0→Ξ-π+)=0.123±0.007±0.010 for the first time. Taking into account the branching fraction of the normalization mode, the absolute branching fractions are determined to be B(Ξc0→ΛKS0)=(3.27±0.11±0.17±0.73)×10-3, B(Ξc0→Σ0KS0)=(0.54±0.09±0.06±0.12)×10-3, and B(Ξc0→Σ+K-)=(1.76±0.10±0.14±0.39)×10-3. The first and second uncertainties above are statistical and systematic, respectively, while the third ones arise from the uncertainty of the branching fraction of Ξc0→Ξ-π+.",
