Search for $Λ ˉ$ - $Λ$ oscillations in the decay $J / ψ \to p K^{-} Λ ˉ + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +454

We report the first search for $Λ ˉ$ -- $Λ$ oscillations in the decay $J / ψ \to p K^{-} Λ ˉ + c . c .$ by analyzing $1.31 \times 1 0^{9}$ $J / ψ$ events accumulated with the BESIII detector at…

Study of BESIII Trigger Efficiencies with the 2018 $J / ψ$ Data

BESIII Collaboration, M. Ablikim, M. N. Achasov +489

Using a dedicated data sample taken in 2018 on the $J / ψ$ peak, we perform a detailed study of the trigger efficiencies of the BESIII detector. The efficiencies are determined from…
