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…

Search for invisible decays of the $Λ$ baryon

BESIII Collaboration, M. Ablikim, M. N. Achasov +498

A search for invisible decays of the $Λ$ baryon is carried out in the process $J / ψ \to Λ Λ ˉ$ based on $(1.0087 \pm 0.0044) \times 1 0^{10}$ $J / ψ$ events collected with the BESIII detect…

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…
