- Abstract
We present measurements of the Cabibbo-suppressed decays Λc+→Λ0K+and Λc+→Σ0K+(both first observations), Λc+→Σ+K+π−(seen with large statistics for the first time), Λc+→pK+K−and Λc+→pφ(measured with improved accuracy). Improved branching ratio measurements for the decays Λc+→Σ+K+K−and Λc+→Σ+φ, which are attributed to W-exchange diagrams, are shown. We also present the first evidence for Λc+→Ξ(1690)0K+and set an upper limit on the non-resonant decay Λc+→Σ+K+K−. This analysis was performed using 32.6 fb−1of data collected by the Belle detector at the asymmetric e+e−collider KEKB.

- Abstract
We have found the first evidence for the Cabibbo suppressed, color suppressed decay B → ψπ in a data sample of 4 million B decays obtained by the CLEO detector at the Cornell Electron Storage Ring (CESR). The branching ratio is found to be (4.3±2.3)% of the Cabibbo allowed B → ψ K decay mode, which is consistent with theoretical expectations.
