Measurements of the Absolute Branching Fraction of the Semileptonic Decay $Ξ^{-} \to Λ e^{-} ν ˉ_{e}$ and the Axial Charge of the $Ξ^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +685

Using $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, we study the semileptonic decay $Ξ^{-} \to Λ e^{-} ν ˉ_{e}$ for the first time at an electron-…

Observation of the decay $ψ (3686) \to Σ^{0} Σ ˉ^{0} ω$

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

Using a dataset of $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ events collected by the BESIII detector operating at the BEPCII collider, we report the first observation of the decay $…
