摘要：

We report the observation of the Cabibbo-suppressed decays Lambda(c)(+) --> pK(-)K(+) and Lambda(c)(+) --> p phi using data collected with the CLEO II detector at CESR. The latter mode, observed for the first time with significant statistics, is of interest as a test of color suppression in charm decays. We have determined the branching ratios for these modes relative to Lambda(c)(+) --> pK(-) pi(+) and compared our results with theory.
