Description
Using a 980 fb-1 data sample collected with the Belle detector on or near Y(nS), n=1, 2, ..., 5, the production cross sections of e+e- →K+K-J/Ψ, KsKs J/Ψ, ɣ χcJ, π+π-Ψ(2S) are measured. The properties of the Y(4360) and Y(4660) in π+π-Ψ(2S) mode are updated, and no significant signal is observed in ɣ χcJ, mode, except those from the Ψ(2S) decays. The possible charged charmoniumlike structures are also searched for in the K±J/Ψ and π±Ψ(2S)intermediate states.
