Recent progress on the study of the charmoniumlike states
  In this article, we review the recent experimental studies on the charmoniumlike states, mainly from the e+e- annihilation experiments BESIII, Belle, BaBar, and CLEO-c, and the hadron collider experiment LHCb. We discuss the results on the X(3872), the vector Y states [Y(4008), Y(4660), and those in e+e- to pi+pi-h_c], and the charged charmoniumlike Z_c^- states.
