Abstract
We study hadronic transitions between bottomonium states using data collected at the resonance with the Belle detector at the KEKB asymmetric energy collider. We measure , , and . We measure the ratio of branching fractions . We search for the decay , but do not find significant evidence for such a transition. We also measure the initial-state radiation production cross sections of the resonances and we find values compatible with the expected ones. Finally, the analysis of the events shows indications for a resonant contribution due to the meson.
