Observation of the Cabibbo Suppressed Charmed Baryon Decay

TL;DR

This paper reports the first observation of certain Cabibbo-suppressed decays of the  baryon, providing experimental data to test theoretical models of charm decay mechanisms.

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.
