Abstract
We have searched for the decay of Υ{hooked}'s into a monochromatic photon accompanied by other particles as a signal for the reaction Υ{hooked}→γ+Higgs. Two different methods are presented both with null result. While we are not sensitive to the branching ratios predicted by the standard model with a minimal Higgs content, we can put limits on the possible values of the lowest Higgs mass and the ratio of the vacuum expectation values for more complex models. Our results are also of interest with respect to the ξ(2.2) being a Higgs in the context of such models. © 1984.
