title = "Observation of Cabibbo-suppressed and W-exchange Λc + baryon decays",
abstract = "We present measurements of the Cabibbo-suppressed decays Λ + c → Λ0K + and Λ + c → Λ0K + (both first observations), Λ + c → Λ + K + π - (seen with large statistics for the first time), Λ + c → pK + K - and Λ + c → pφ (measured with improved accuracy). Improved branching ratio measurements for the decays Λ + c → Λ + K + K - and Λ + c → Λ + φ, which are attributed to W-exchange diagrams, are shown. We also present the first evidence for {equation presented} and set an upper limit on the non-resonant decay Λ + c → Λ + K + K-. This analysis was performed using 32.6 fb-1 of data collected by the Belle detector at the asymmetric e + e - collider KEKB.",
