Abstract

Recent progress on the bottomonium states is reported. This talk briefly reviews the observation of $h_b(1P), h_b(2P), Z_{b1}^+, Z_{b2}^+$ states, transition of $h_b(nP)\to \eta_b(mS)\gamma$ and new studies on the $\eta_b(2S)$ state. Other $\eta$ and $\pi^+\pi^-$ transitions of $\Upsilon(nS)$ are also discussed.
