Recent results on charm decays at (radical)s (approx) 10 GeV

摘要

Recent results on decays of charm particles are presented. The CLEO collaboration has measured two body decay modes of D(sub s) involving (eta), (eta)(sup 1) or (rho)(sup +), using the new CLEO 2 detector. They also have new measurements of the branching ratios of the D(sup *0) and D(sup *+). In charm baryon decays, results from CLEO 2 are presented for (Lambda)(sub c)(sup +) (yields) (Sigma)(sup 0)(pi)(sup +), (Lambda)(sub c)(sup +) (yields) (Lambda)(pi)(sup +)(pi)(sup 0), and the W-exchange process (Xi)(sub c)(sup 0) (yields) (Omega)(sup (minus)) K(sup +) has been observed in the CLEO 1 data. 31 refs., 20 figs., 6 tabs.
