The role of charged exotic states in e+e− → ψ(2S) π+π−
In this work, we use the dispersion theory to provide a physical description of recent BESIII data on the reaction e+e−→ψ(2S)π+π−. Taking into account explicitly the effects of charged exotic intermediate states in the t- and u-channels as well as the two-pion final state interaction, we describe th...
