Exotic and Charmonium(-like) states at BESIII

The BESIII Experiment at the Beijing Electron Positron Collider (BEPCII) has accumulated the world's largest samples of direct $e^+e^-$ collisions in the tau-charm region. From the collected samples, which include $e^+e^-$ annihilations at J/psi, psi(2S), psi(3770) peaks and in the region from 3.8 GeV to 4.6 GeV, BESIII has produced many new physics results in the spectroscopy, transitions, and decays of charmonium(-like) states. This talk will cover the latest results over a wide range of topics from radiative and hadronic transitions among charmonium states, as well as the productions and decays of the $XYZ$ states.
