We have observed four new decay modes of the charmed baryon + c using data collected with the CLEO II detector. Three decay modes, + c ! p K 0 , + , and + , are rst observations of nal states with an meson, while the fourth mode, + c ! K 0 K + , requires an s s quark pair to be popped out of the vacuum. The branching ratios relative to + c ! pK ? + are(More)
We have fully reconstructed decays of both B 0 and B mesons into nal states containing either D, D , D , , 0 or c1 mesons. This allows us to obtain new results on many physics topics including branching ratios, tests of the factorization hypothesis, color suppression, resonant substructure, and the B B 0 mass diierence.
Using data recorded by the CLEO-II detector at CESR, we report the rst observation of an excited charmed baryon decaying into 0 c +. The state has mass diierence M((0 c +) ? M((0 c) of 174:3 0:5 1:0 MeV=c 2 , and a width of < 3:1 MeV=c 2 (90% conndence level limit). We identify the new state as the + c , the isospin partner of the recently discovered 0 c. 2(More)
We report new measurements of the differential and total branching ratios for inclusive B decay to D 0 , D + and D * + and the first measurement of the same quantities for inclusive B decay to D * 0. Here B is the mixture of B d and Bu from Υ(4S) decay. Furthermore, since more than one charm particle (or antiparticle) of the same kind can be produced in B(More)
