Abstract
We have studied the topologies of hadronic events in e+e- annihilation data taken in the region of the upsilon resonances with the non-magnetic CUSB detectors at CESR. Using a thrust-like variable we compare the decay of Υ{hooked}, Υ{hooked}′ and Υ{hooked}Prime; find for Υ{hooked}″ a significant excess of high thrust events, which we interpret as evidence for electric dipole transitions. © 1982.
