# Charmonium and Charm Spectroscopy

## TL;DR

This paper reviews recent experimental progress in charmonium and charm spectroscopy, highlighting new state observations, parameter measurements, and the identification of excited and exotic charm hadrons from major collider experiments.

## Contribution

It provides a comprehensive overview of recent experimental discoveries and measurements in charmonium and charm spectroscopy, including new state observations and parameter determinations.

## Key findings

- Observation of $oxed{ ext{psi}(1^{3}D_{3})}$ candidate
- Measurement of resonant parameters of $oxed{ ext{chi}_{cJ}}$, $oxed{ ext{eta}_c}$, $oxed{ ext{eta}_c(2S)}$
- Discovery of excited $B_c$, $ ext{Xi}(2930)$, $ ext{Omega}_c$ states and doubly charm baryons

## 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 $\Lambda_{c}^{*}$ states.
