M. N. Achasov, O. Albayrak, D. Ambrose, F. F. An et autres

We present a precision study of the ${\ensuremath{\psi}}^{\ensuremath{'}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}J/\ensuremath{\psi}$ and $\ensuremath{\eta}J/\ensuremath{\psi}$ decay modes. The measurements are obtained using $106\ifmmode\times\else\texttimes\fi{}{10}^{6}$ ${\ensuremath{\psi}}^{\ensuremath{'}}$ events accumulated with the BESIII detector at the BEPCII ${e}^{+}{e}^{\ensuremath{-}}$ collider operating at a center-of-mass energy corresponding to the ${\ensuremath{\psi}}^{\ensuremath{'}}$ mass. We obtain …
