Abstract
We report results of a study of exotic charmonium-like states using the data sample accumulated with the Belle detector at the KEKB asymmetric-energy e+e− collider. A search for X(3872) decays to final states with the ηc is presented. We report evidence for a χc1γ mode in the decay B→χc1γK. A study of e+e−→π+π−J/ψ and an observation of a new charmonium-like resonance are described. Also observed are ψ(4040) and ψ(4160) decays to ηJ/ψ.
