Based on electron positron collision data collected with the BESIII detector operating at the BEPCII storage rings, the differential cross sections of inclusive π^{0} and K_{S}^{0} production as a function of hadron momentum, normalized by the total cross section of the e^{+}e^{-}→hadrons …

We report the observation and study of the decay $J/\ensuremath{\psi}\ensuremath{\rightarrow}\ensuremath{\phi}\ensuremath{\eta}{\ensuremath{\eta}}^{\ensuremath{'}}$ using $1.3\ifmmode\times\else\texttimes\fi{}1{0}^{9}$ $J/\ensuremath{\psi}$ events collected with the BESIII detector. Its branching fraction, including all possible intermediate states, is measured to be $(2.32\ifmmode\pm\else\textpm\fi{}0.06\ifmmode\pm\else\textpm\fi{}0.16)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$. We also report evidence for a structure, denoted as $X$, …
