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 leptonic decay $D^{+} \to τ^{+} ν_{τ}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +479

We report the first observation of $D^{+} \to τ^{+} ν_{τ}$ with a significance of $5.1 σ$ . We measure ${\cal B}(D^+\toτ^+ν_τ) = (1.20\pm0.24_{\text{stat.}}\pm0.12_{\text{syst.}})\times10^{-3…

Observation of $ψ (3686) \to e^{+} e^{-} χ_{c J}$ and $χ_{c J} \to e^{+} e^{-} J / ψ$

M. Ablikim, M. N. Achasov, X. C. Ai +420

Using $4.479 \times 1 0^{8}$ $ψ (3686)$ events collected with the BESIII detector, we search for the decays $ψ (3686) \to e^{+} e^{-} χ_{c 0, 1, 2}$ and $χ_{c0,1,2} \rightarrow e^{…
