Abstract
We report the measurement of new modes of the charmed baryon LAMBDA(c)+ using data recorded by the CLEO II detector at the Cornell Electron Storage Ring. We find branching ratios, relative to LAMBDA(c)+ --> pK-pi+, of 0.070 +/- 0.011 +/- 0.011 for LAMBDA(c)+ --> SIGMA+K+K-, 0.069 +/- 0.023 +/- 0.016 for LAMBDA(c)+ --> SIGMAphi, 0.078 +/- 0.013 +/- 0.013 for LAMBDA(c)+ --> XI0K+, and 0.053 +/- 0.016 +/- 0.010 for LAMBDA(c)+ --> XI*0K+. These measurements indicate that W-exchange diagrams contribute to LAMBDA(c)+ decay. We have also made a new measurement of the previously found mode LAMBDA(c)+ --> XI-K+pi+.
