Potential Physics at a Super τ-charm Factory


With its unique data samples at energies of 3.8–4.6 GeV, the BESIII experiment made a significant contribution to the study of charmonium and charmonium-like states, i.e., the XYZ states.We review the results for observations of the Zc3900 and Zc4020 states, the X3872 in ee annihilation, and charmonium ?1 D2 state, as well as measurements of the cross-sections of ??cJ and ?J-?, and the search for ee ? ??cJ and ?Y 4140. We also present data from BESIII that may further strengthen the study of the XYZ and conventional charmonium states, and discuss perspectives on future experiments.
