Abstract
We have searched for radiative decays of the Υ{hooked}(1 S) resonance, Υ{hooked}(1 S)→γX, where X is one of the mesons η, η′f2 (1270), f2 (1720), or a narrow resonance with mass less than 3 GeV/c2 which decays into either π0π0 or ηη. The mesons are identified in their all-neutral decay modes. Since we do not find any such decays, we calculate upper limits on the corresponding branching ratios. These limits are compared to theoretical predictions and to the corresponding branching ratios measured in radiative J/Ψ decays.
