Exotic and Charmonium(-like) states at BESIII

Abstract

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 $J/\psi$, ${\psi }^{\prime }$, $\psi$(3770) peaks and in the region from 3.8GeV to 4.6GeV, 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.
