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 studied the effect of breathing at various levels of transdiaphragmatic pressure (Pdi) on the EMG power spectrum of the diaphragm. The diaphragmatic EMG was measured simultaneously with a bipolar esophageal electrode (EE) and surface electrode (SE) placed on the ventral portion of the sixth and seventh intercostal spaces in five normal subjects breathing(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.
We have studied semileptonic B meson decays with a P-wave charm meson in the nal state using 3:29 10 6 B B events collected by the CLEO II detector at the Cornell Electron-positron Storage Ring. We nd a value for the exclusive semileptonic product branching fraction: These results indicate that at least 20% of the total B ? semileptonic rate is un-accounted(More)
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 have measured the branching fractions for B → ¯ DX, B → DX, and B → ¯ DXℓ + ν, where " B " is an average over B 0 and B + , " D " is a sum over D 0 and D + , and " ¯ D " is a sum over ¯ D 0 and D −. From these results and some previously measured branching fractions, we obtain B(b → c¯ cs) = (21.9 ± 3.7)%, B(b → sg) < 6.8% @ 90% c.l, and B(D 0 → K − π +)(More)
