Abstract: Inspired by the recent observation of the charged charmoniumlike structure Zc(4025) , we explore the Y(4260)(DD¯)-π+ decay through the initial-single-pion-emission mechanism, where the DD¯DD¯ interaction is studied by the ladder approximation, including the non-interacting case. Our calculation of the differential decay width for Y(4260)(DD¯)-π+ indicates that a charged enhancement structure around DD¯ appears in the DD¯ invariant mass spectrum for this process, which might correspond to the newly observed Zc(4025) structure.
