Charged charmoniumlike structures in the $$e^+ e^- \rightarrow \psi (3686) \pi ^+ \pi ^-$$ e+e-→ψ(3686)π+π- process based on the ISPE mechanism
Abstract In 2017, the BESIII Collaboration announced the observation of a charged charmonium-like structure in the $$\psi (3686)\pi ^\pm $$ ψ(3686)π± invariant mass spectrum of the $$e^+ e^- \rightarrow \psi (3686) \pi ^+ \pi ^-$$ e+e-→ψ(3686)π+π- process at different energy points, which enables us...
