abstract

  • Continuing our studies of radiative (Formula presented) decays, we report on a search for (Formula presented) and (Formula presented) in (Formula presented) (Formula presented) of (Formula presented) data taken with the CLEO II detector at the Cornell Electron Storage Ring. For the (Formula presented) search the three decays of the (Formula presented) meson to (Formula presented) (Formula presented), and (Formula presented) were investigated. We found no candidate events in the (Formula presented) modes and no significant excess over expected backgrounds in the (Formula presented) mode to set a limit on the branching fraction of (Formula presented) at (Formula presented) C.L. The three charged two-body final states (Formula presented) were investigated for (Formula presented) production, with one, one, and two events found, respectively. Limits at (Formula presented) C.L. of (Formula presented) have been set for each of these modes. We compare our results to measurements of other radiative (Formula presented) decays, to measurements of radiative (Formula presented) decays, and to theoretical predictions. 2002 The American Physical Society.
