Observation of a neutral charmoniumlike state $Z_c(4025{)}^0$ in $e^{+}{e}^{-}\to (D^{\ast }{\bar{D}}^{\ast }{)}^0{\pi }^0$

BESIII collaboration, M. Ablikim, M. N. Achasov +414

We report a study of the process $e^{+}{e}^{-}\to (D^{\ast }{\bar{D}}^{\ast }{)}^0{\pi }^0$ using $e^{+}{e}^{-}$ collision data samples with integrated luminosities of $1092{\mathrm{pb}}^{-1}$ at $\sqrt{s…
