Abstract

Using data taken with the CLEO III detector, 1.09fb-1 at Υ(1S) and 1.28fb-1 at Υ(2S), branching fractions have been measured for the first time for exclusive decays of each resonance into different final states consisting of 4-10 light hadrons, pions (including up to 2π0), kaons, and protons. Significant strength is found in 73 decay modes of Υ(1S) and 17 decay modes of Υ(2S), with branching fractions ranging from 0.3×10-5 to 110×10-5. Upper limits at 90% confidence level are presented for the other decay modes.
