Abstract

We report the measurement of new modes of the charmed baryon Λc+ using data recorded by the CLEO II detector at the Cornell Electron Storage Ring. We find branching ratios, relative to Λc+→pK-π+, of 0.070±0.011±0.011 for Λc+→+K+K-, 0.069±0.023±0.016 for Λc+→φ, 0.078±0.013±0.013 for Λc+→Ξ0K+, and 0.053±0.016±0.010 for Λc+→Ξ*0K+. These measurements indicate that W-exchange diagrams contribute to Λc+ decay. We have also made a new measurement of the previously found mode Λc+→Ξ-K+π+.
