Abstract

In this talk, we present the recent study on the charmoniumlike states from the e^+e^- colliders, including BESIII, Belle, BaBar, and CLEOc. The talk covers the X(3872) from the Y(4260) radiative transition, the Y states from the initial-state-radiation processes and from e+e- to pi+pi-h_c, and the charged Z_c states.
