The direct decay into four and more charged particles of the Υ{hooked}(9.46) formed in e+e- collisions is analysed for hadron-jet configurations. The results are compared with the expectations of phase space, a qq two-jet model and a QCD three-gluon decay mechanism. Out of these three models, the three-gluon decay describes best the data.
