New and conventional bottomonium states

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 ${\rm Y}(nS)$ are also discussed.
