Abstract
Based on a data sample of 983 fb−1 collected with the Belle detector at the KEKB asymmetric-energy e+e− collider, we present the study of the heavy-flavor-conserving decay Ξ0c→Λ+cπ− with Λ+c reconstructed via its pK−π+ decay mode. The branching fraction ratio B(Ξ0c→Λ+cπ−)/B(Ξ0c→Ξ−π+) is measured to be 0.38±0.04±0.04. Combing with the world average value of B(Ξ0c→Ξ−π+), the branching fraction B(Ξ0c→Λ+cπ−) is deduced to be (0.54±0.05±0.05±0.12)%. Here, the uncertainties above are statistical, systematic, and from B(Ξ0c→Ξ−π+), respectively.File in questo prodotto:
