Description
The largest data sample accumulated by the Belle experiment at KEKB asymmetric energy e+e- collider provides an opportunity to perform studies of bottomonia. We report on the study of bottomonium production in association with an eta meson in e+ e- annihilations near Y(5S), and the measurement of e+ e^ → chi_bJ phi, chi_bJ omega near Y(6S). We also present the measurement of the decays Y(4S) → eta' Y(1S), Y(2S) → gamma eta_b and Y(1S,2S) → Zc Zc, where Zc is the exotic charmonium-like resonance. Measurements other charmonium-like resonances are also reported.
