Abstract

We report the first observation of the Cabibbo-suppressed decays Ξc0→Ξ^-K⁺, Ξc0→ΛK ⁺K^- and Ξc0→Λφ, using a data sample of 711 fb^-1 collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e⁺e^- collider. We measure the ratios of branching fractions to be B(Ξc0→Ξ ^-K⁺)B(Ξc0→Ξ^-π⁺)=(2. 75±0.51±0.25)×10^-2, B(Ξc0→ΛK ⁺K^-)B(Ξc0→Ξ^-π⁺)=(2. 86±0.61±0.37)×10^-2 and B(Ξc0→Λ φ)B(Ξc0→Ξ^-π⁺)=(3.43±0. 58±0.32)×10^-2, where the first uncertainty is statistical and the second is systematic.
