abstract = "Using data samples of 983.0 fb−1 and 427.9 fb−1 accumulated with the Belle and Belle II detectors operating at the KEKB and SuperKEKB asymmetric-energy e+e− colliders, singly Cabibbo-suppressed decays Ξc+→pKS0, Ξc+→Λπ+, and Ξc+→Σ0π+ are observed for the first time. The ratios of branching fractions of Ξc+→pKS0, Ξc+→Λπ+, and Ξc+→Σ0π+ relative to that of Ξc+→Ξ−π+π+ are measured to be (Formula presented.) Multiplying these values by the branching fraction of the normalization channel, BΞc+→Ξ−π+π+=2.9±1.3\%, the absolute branching fractions are determined to be (Formula presented.) The first and second uncertainties above are statistical and systematic, respectively, while the third ones arise from the uncertainty in BΞc+→Ξ−π+π+.",
