| 英文摘要 | We present measurements of the Cabibbo-suppressed decays Lambda(c)(+) --> Lambda(0)K(+) and Lambda(c)(+) --> Sigma(0)K(+) (both first observations), Lambda(c)(+) --> Sigma(+)K(+)pi(-) (seen with large statistics for the first time), Lambda(c)(+) --> pK(+)K(-) and Lambda(c)(+) --> pphi (measured with improved accuracy). Improved branching ratio measurements for the decays Lambda(c)(+) --> Sigma(+)K(+)K(-) and Lambda(c)(+) --> Sigma(+)phi, which are attributed to NV-exchange diagrarns, are shown. We also present the first evidence for Lambda(c)(+) --> Xi(1690)(0)K(+) and set an upper limit on the non-resonant decay Lambda(c)(+) --> Sigma(+)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, (C) 2002 Elsevier Science B.V. All rights reserved. |
