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 $e^{+} e^{-} \to Σ^{0} Σ ˉ^{0}$ cross sections at center-of-mass energies from $2.3864$ to $3.0200$ GeV

M. Ablikim, M. N. Achasov, P. Adlarson +484

The Born cross sections of $e^{+} e^{-} \to Σ^{0} Σ ˉ^{0}$ are measured at center-of-mass energies from $2.3864$ to $3.0200$ GeV using data samples with an integrated luminosity of…

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…
