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…
