Abstract
Recent results on spectroscopy from Belle are reviewed. Belle searches for the charged Zb states in ϒ(5S)→B⁎B(⁎)π± decays and for the neutral Zb partner in ϒ(5S)→π0π0ϒ(nS) decays. The properties of the X(3872) state are updated with Belleʼs full data sample, and its charged partner is probed in the ρ+J/ψ final state. Belle searches for the C-odd neutral partner of the X(3872) in the ηJ/ψ and γχc1 final states. The ψ2 charmonium state is observed for the first time in the γχc1 final state. A scan of e+e−→ηJ/ψ via initial state radiation shows obvious ψ(4040) and ψ(4160) signals but no evidence for an exotic Y state. The partial widths of ψ(4040) and ψ(4160) decaying to ηJ/ψ are found to be of order 1 MeV.
