Simulating the charged charmoniumlike structure $$Z_c(4025)$$

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