The Born cross sections of the process $e^{+}e^{-}\to D^{*0}D^{*-}π^{+}$ at center-of-mass energies from 4.189 to 4.951 GeV are measured for the first time. The data samples used correspond to an integrated luminosity of $17.9\,{\rm fb}^{-1}$ and were collected by the BESIII detector …

Using data taken at 29 center-of-mass energies between 4.16 and 4.70 GeV with the BESIII detector at the Beijing Electron Positron Collider corresponding to a total integrated luminosity of approximately 18.8 $\rm fb^{-1}$, the process $e^+e^- \to p p \bar{p} \bar{n} π^{-} …

Based on a sample of $448.1\times10^6\ ψ(3686)$ events collected with the BESIII detector, a study of $ψ(3686)\toΛ\barΛπ^0$ and $ψ(3686)\toΛ\barΛη$ is performed. Evidence of the isospin-violating decay $ψ(3686)\toΛ\barΛπ^0$ is found for the first time with a statistical significance of $3.7σ$, the branching fraction …
