Simulating the charged charmoniumlike structure $Z_c(4025)$

Inspired by recent observation of charged charmoniumlike structure $Z_c(4025)$, we explore the $Y(4260)\to (D^*\bar{D}^*)^- π^+$ decay through the initial-single-pion-emission mechanism, where the $D^*\bar{D}^*\to D^*\bar{D}^*$ interaction is studied by the ladder approximation including a non-interacting case. Our calculation of the differential decay width for $Y(4260)\to (D^*\bar{D}^*)^- π^+$ indicates that a charged enhancement structure around $D^*\bar{D}^*$ appears in the $D^*\bar{D}^*$ invariant mass spectrum for this process, which can correspond to newly observed $Z_c(4025)$ structure.
