Contribution
It presents the first observation of the decay mode , and measures their branching ratios relative to known decays, testing color suppression in charm decays.
Findings
First observation of decay mode.
Measured branching ratios for the observed decays.
Results compared with theoretical predictions.
Abstract
We report the observation of the Cabibbo-suppressed decays \lcpkk\ and \lcpphi\ 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 \lcpkpi\ and compared our results with theory.
