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-…

Study of the $h_{c}$ ( $1^{1} P_{1}$ ) meson via $ψ (2 S) \to π^{0} h_{c}$ decays at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +549

Using 448 million $ψ (2 S)$ events, the spin-singlet $P$ -wave charmonium state $h_{c}$ (1 $^{1} P_{1}$ ) is studied via the $ψ (2 S) \to π^{0} h_{c}$ decay followed by the $h_{c} \to γ η_{c}$ tra…

Observation of a state $X (2600)$ in the $π^{+} π^{-} η^{'}$ system in the process $J / ψ \to γ π^{+} π^{-} η^{'}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +556

Based on $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, the process $J / ψ \to γ π^{+} π^{-} η^{'}$ is studied using two dominant decay channels of the $…

First Measurement of the Absolute Branching Fraction of $Λ \to p μ^{-} ν ˉ_{μ}$

M. Ablikim, M. N. Achasov, P. Adlarson +504

The absolute branching fraction of $Λ \to p μ^{-} ν ˉ_{μ}$ is reported for the first time based on an $e^{+} e^{-}$ annihilation sample of ten billion $J / ψ$ events collected with the BESII…

Observation of the semi-muonic decay $D^{+} \to ω μ^{+} ν_{μ}$

BESIII Collaboration

We report the first observation of the semi-muonic decay $D^{+} \to ω μ^{+} ν_{μ}$ using an $e^{+} e^{-}$ collision data sample corresponding to an integrated luminosity of $2.93~\mathrm{fb}^{-1…

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…
