Abstract
In a sample of produced mesons we have observed decays , with branching fractions and . We have searched with comparable sensitivity for 17 related decays to final states containing an or meson accompanied by a single particle or low-lying resonance. Our upper limits for these constrain theoretical interpretations of the signal.
