Further experimental studies of two-body radiative decays Academic Article uri icon


  • Continuing our studies of radiative decays, we report on a search for and fj(2220) in 61.3 pb-1 of e+e- data taken with the CLEO II detector at the Cornell Electron Storage Ring. For the search the three decays of the meson to + - 0, 0 0 0, and were investigated. We found no candidate events in the (3 )0 modes and no significant excess over expected backgrounds in the mode to set a limit on the branching fraction of B(Y)< 2.1 10-5 at 90% C.L. The three charged two-body final states hh(h = +, K+, p) were investigated for fj(2220) production, with one, one, and two events found, respectively. Limits at 90% C.L. of B(fj) B(fjhh) 1.5 10-5 have been set for each of these modes. We compare our results to measurements of other radiative decays, to measurements of radiative J/ decays, and to theoretical predictions.
