Using $1310.6times10^{6}$ $J/psi$ and $448.1times10^{6}$ $psi(3686)$ events collected with the BESIII detector, the branching fractions of $J/psi$ and $psi(3686)$ decays to $Sigma^{+}overline{Sigma}^{-}$ are measured to be $(10.61 pm 0.04 pm 0.36) times 10^{-4}$ and $(2.52 pm 0.04 pm 0.09) times 10^{-4}$, respectively. In addition, the ratio of $mathcal{B}(psi(3686) rightarrow Sigma^{+}overline{Sigma}^{-})/mathcal{B}(J/psi rightarrow Sigma^{+}overline{Sigma}^{-})$ is determined to be $(23.8 pm 1.1)%$ which violates the $12%$ rule.
From $1310.6times10^{6}$ $J/psi$ and $448.1times10^{6}$ $psi(3686)$ events collected with the BESIII experiment, we report the first observation of $Sigma^{+}$ and $bar{Sigma}^{-}$ spin polarization in $e^+e^-rightarrow J/psi (psi(3686)) rightarrow S
Using $1310.6times10^6$ $J/psi$ and $447.9times10^6$ $psi(3686)$ events collected with the BESIII detector at the BEPCII $e^{+}e^{-}$ collider, the branching fractions and the angular distributions of $J/psi$ and $psi(3686)$ decays to $Lambdabar{Lamb
Using a data sample of $448times10^{6}$ $psi(3686)$ events collected with the BESIII detector operating at the BEPCII storage ring, the decays $psi(3686)rightarrowgammaeta$ and $psi(3686)rightarrowgammapi^{0}$ are observed with a statistical signific
Based on $4.481times10^8$ $psi(3686)$ events collected with the BESIII detector at BEPCII, the branching fraction of the isospin violating decay $psi(3686)rightarrowbar{Sigma}^{0}Lambda+c.c.$ is measured to be $(1.60 pm 0.31 pm 0.13~pm~0.58) times 10
Using the data samples of $1.31times 10^9$ $J/psi$ events and $4.48times 10^8$ $psi(3686)$ events collected with the BESIII detector, partial wave analyses on the decays $J/psi$ and $psi(3686) to pi^+pi^-eta^prime$ are performed with a relativistic c
