abstract = "The Cabbibo-favored decay Λc+→Ξ0K+π0 is studied for the first time using 6.1 fb-1 of e+e- collision data at center-of-mass energies between 4.600 and 4.840 GeV, collected with the BESIII detector at the BEPCII collider. With a double-tag method, the branching fraction of the three-body decay Λc+→Ξ0K+π0 is measured to be (7.79±1.46±0.95)×10-3, where the first and second uncertainties are statistical and systematic, respectively. The branching fraction of the two-body decay Λc+→Ξ(1530)0K+ is (5.99±1.04±0.32)×10-3, which is consistent with the previous result of (5.02±0.99±0.31)×10-3. In addition, the upper limit on the branching fraction of the doubly Cabbibo-suppressed decay Λc+→nK+π0 is 7.1×10-4 at the 90% confidence level. The upper limits on the branching fractions of Λc+→ς0K+π0 and ΛK+π0 are also determined to be 1.8×10-3 and 2.0×10-3, respectively. ",
