Description
Charmonium decays offer a promising hunting ground for the investigation of light QCD exotics, particularly gluonic excitations such as glueballs and hybrids. These particles are expected to be copiously produced in the gluon-rich environment characteristic of charmonium decays. In this talk, we will report on the discovery of a glueball-like state, X(2370). Additionally, we will present recent advancements in the study of spin-exotic 1-+ states, eta(1855) and pi1(1600). Furthermore, the observation of the anomalous shape of X(1840) in J/psi->gamma 3(pi+pi-) will be presented as well.
