N2 - Utilizing 4.5 fb−1 of e+e− annihilation data collected at center-of-mass energies ranging from 4599.53 MeV to 4698.82 MeV by the BESIII detector at the BEPCII collider, we searched for singly Cabibbo-suppressed hadronic decays Λ+c → Σ0K+π0 and Λ+c → Σ0K+π+π− with a single-tag method. No significant signals were observed for both decays. The upper limits on the branching fractions at the 90% confidence level were determined to be 5.0×10−4 for Λ+c → Σ0K+π0 and 6.5×10−4 for Λ+c → Σ0K+π+π−.
