This paper summarizes what we have done sofar to explain charged charmonium/bottomonium-like structures using a hadronic triangle diagram which we call the initial single chiral particle emission mechanism. We discuss processes like A→A' +P+P' in which two chiral particles P and P' are emitted from A. In the intermediate we consider a hadronic one-loop diagram in which D(*)/D(*) s /B(*)/B(*)s are included to explain some enhancements experimentally observed. Using this mechanism we explain some of the exotic enhancements and predict a couple of enhancement structures. [ABSTRACT FROM AUTHOR]

Some recent progresses on the charmonium-like states from Belle experiment are reviewed including: (1) A new charged charmonium-like state Zc(4200)+ decaying to J/Ψπ+ is observed with a significance of 6.2σ by performing an amplitude analysis of B0 → J/ΨK-π+ decays. The mass and width of the Zc(4200)+ are 4196+31+17 -29-13 MeV/c2 and 370+70+70 -70-132 MeV, respectively; the preferred JP = 1+; (2) A search for Z± cs resonant structures in the process e+e- → K+K-J/Ψ is performed; (3) The cross sections of e+e- → π+π-Ψ(2S) between 4.0 and 5.5 GeV are updated with full of data sample (980 fb-1). The properties of the Y(4360) and Y(4660) states are determined with improved precision. Evidence for a charged charmonium-like structure at 4.05 GeV/c2 is observed in the π±Ψ(2S) intermediate state in the Y(4360) decays. [ABSTRACT FROM AUTHOR]
