AB - Using the ARGUS detector at the DORIS II storage ring we have searched for radiative decays Υ(1 S)→γX, where X decays into two oppositely charged pions, kaons, or protons. Upper limits on branching fractions are presented. In the π<inf>+</inf>π<inf>-</inf> invariant mass region 290-570 MeV/c<sup>2</sup> the upper limit obtained varies from 3 to 4.5×10<sup>-5</sup>. These values are lower than the theoretical prediction of about 5×10<sup>-5</sup> for Higgs production, which includes perturbative QCD radiative corrections to the Wilczek formula and the estimate Br(H<inf>0</inf>→π<inf>+</inf>π<inf>-</inf>), accounting for Higgs coupling to gluons via heavy quark loops. Previous experimental results do not exclude the existence of a standard minimal Higgs in this mass region. © 1989 Springer-Verlag.
