Number of $J/ ψ$ events at BESIII

BESIII Collaboration

Using inclusive decays of the $J/ ψ$ , a precise determination of the number of $J/ ψ$ events collected with the BESIII detector is performed. For the two data sets taken in 2…

Observation of $J / ψ$ decays to $e^{+} e^{-} e^{+} e^{-}$ and $e^{+} e^{-} μ^{+} μ^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +543

Using a data sample of $4.481 \times 1 0^{8} ψ^{'}$ events collected with the BESIII detector, we report the first observation of the four-lepton-decays $J / ψ \to e^{+} e^{-} e^{+} e^{-}$ and $J…

Measurement of the absolute branching fractions of Jpsi to gamma eta and eta decay modes

BESIII Collaboration

Based on a data sample of (1.0087+-0.0044)x10^10 Jpsi events collected by the BESIII detector at the BEPCII accelerator, the absolute branching fraction (BF) of the decay Jpsi->gam…

Observation of $ψ (3686) \to Ξ (1530)^{0} Ξ ˉ (1530)^{0}$ and $Ξ (1530)^{0} Ξ ˉ^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +504

Using $(448.1 \pm 2.9) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector and a single-baryon tagging technique, we present the first observation of the decays $ψ(3686…
