First Measurements of Exclusive Hadronic Decays of Upsilon(1S) and Upsilon(2S)
Abstract
Using data taken with the CLEO III detector, 1.09 fb-1 at Upsilon(1S), and 1.28 fb-1 at Upsilon(2S), branching fractions have been measured for the first time for exclusive decays of each resonance into one hundred different final states consisting of 4 to 10 light hadrons, pions, kaons, and protons. Significant strength is found in 73 decay modes of Upsilon(1S) and 17 decay modes of Upsilon(2S), with branching fractions ranging from 0.3x10-5 to 110x10-5. Upper limits at 90% confidence level are presented for the other decay modes.
