Abstract

We report on a study of exclusive radiative decays Υ(nS) →γ+R (n=1, 2, 3), with R a narrow resonant hadronic state decaying into four or more charged particles (plus possible neutrals). Using data collected from the CLEO III detector at the Cornell Electron Storage Ring, we present upper limits of order 10-4 for such bottomonium two-body decays as a function of the mass MR recoiling opposite the photon.
