Query: Simulating the charged charmoniumlike structure $Z_c(4025)$   Inspired by recent observation of charged charmoniumlike structure
$Z_c(4025)$, we explore the $Y(4260)\to (D^*\bar{D}^*)^- \pi^+$ 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
$Y(4260)\to (D^*\bar{D}^*)^- \pi^+$ 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.
