Abstract
Using samples of and events collected with the Belle detector, we study exclusive hadronic decays of these two bottomonium resonances to the three-body final states , and , and to the two-body Vector-Tensor states (, , and ) and Axial-vector-Pseudoscalar (, and ) states. Signals are observed for the first time in the , , , and , decay modes. Branching fractions are determined for all the processes, while 90% confidence level upper limits are established on the branching fractions for the modes with a statistical significance less than . The ratios of the branching fractions of and decays into the same final state are used to test a perturbative QCD prediction for OZI-suppressed bottomonium decays.
