Charmonium and Charm Spectroscopy

Abstract

In this talk, we review the recent experimental developments on charmonium and charm spectroscopy base on the data samples taken by the BESIII, Belle, LHCb and CMS experiments. We concentrate on the resonant parameter measurement of ${\chi }_{cJ}$, ${\eta }_c$, ${\eta }_c(2S)$, observation of $\psi (1^3{D}_3)$ candidate and alternative ${\chi }_{c0}(2P)$ candidate, observation of excited $B_c$ states, $\Xi (2930)$ states, excited ${\Omega }_c$ states and doubly charm baryon, and the study of ${\Lambda }_c^{\ast }$ states.

Talk given at the Flavor Physics and CP Violation Conference, Victoria BC, May 6-10, 2019
