Description
In this talk, some recent results on the non-vector charmonium(-like) states at BESIII will be presented. It will include an observation of a near-threshold enhancement in the Lambda Lambda-bar mass spectrum from e+ e- -> phi Lambda Lambda-bar at sqrt(s) from 3.5 to 4.6 GeV, search for new decay modes of the D-wave state psi(3823) and the process e+ e- -> pi0 pi0 psi(3823), and study of e+ e- -> pi0 X(3872) gamma and search for neutral Zc(4020) radiactive transition to X(3872).
