Deskripsi

We present the recent progress on the charmonium-like states (or called XYZ states) from electron-positron colliders, including the results from BESIII, CLEO-c, BaBar and Belle. This talk covers the observation of X(3872) from radiative decay of the Y(4260), the updated results of Y states from initial state radiation (ISR) process of π+π− J/ψ and π+π−ψ(2S) and also cross section measurement of e+e− → π+π−hc and e+e− → ωχc0, and the observation of charged and neutral charmonium-like states (Zcs).
