Abstract:
Using data collected by the CLEO II detector at a center-of-mass energy on or near the (Formula presented) resonance, we have determined the 90% confidence level upper limit (Formula presented) for electrons with momentum above (Formula presented) We have also obtained the limit (Formula presented) at the 90% confidence level and measured the ratio (Formula presented). 漏 1998 The American Physical Society.Two-Body B meson decays to 畏 and 畏鈥�: Observation of B鈫捨封�睰

Abstract:
In a sample of 6.6脳106 produced B mesons we have observed decays B鈫捨封�睰, with branching fractions B(B+鈫捨封�睰)=(6.5+1.5-1.4卤0.9)脳10-5 and B(B0鈫捨封�睰)=(4.7+2.7-2.0卤0.9)脳10-5. We have searched with comparable sensitivity for 17 related decays to final states containing an 畏 or 畏鈥� meson accompanied by a single particle or low-lying resonance. Our upper limits for these constrain theoretical interpretations of the B鈫捨封�睰 signal. 漏 1998 The American Physical Society.A limit on the mass of the 谓蟿
