Production of $Y(4260)$ as a hadronic molecule state of $\bar{D}{D}_1+c.c.$ in $e^{+}{e}^{-}$ annihilations

Wen Qin, Si-Run Xue, Qiang Zhao

We study the $Y(4260)$ production mechanism in $e^{+}{e}^{-}$ annihilations in the framework of hadronic molecules and investigate the consequence of such a picture in different decay ch…
