Observation of a charged charmoniumlike structure in $e^{+}{e}^{-}\to (D^{\ast }{\bar{D}}^{\ast }{)}^{\pm }{\pi }^{\mp }$ at $\sqrt{s}=4.26$GeV

BESIII collaboration, M. Ablikim, M. N. Achasov +358

We study the process $e^{+}{e}^{-}\to (D^{\ast }{\bar{D}}^{\ast }{)}^{\pm }{\pi }^{\mp }$ at a center-of-mass energy of 4.26GeV using a 827pb${}^{-1}$ data sample obtained with the BESIII detector at the Be…
