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…

Study of the Dalitz decay $J / ψ \to e^{+} e^{-} η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +507

We report corrected results on a study of the electromagnetic Dalitz decay $J / ψ \to e^{+} e^{-} η$ and search for di-electron decays of a light dark gauge boson ( $γ^{'}$ ) in $J / ψ \to γ^{'} η$ w…
