Production and Decay Dynamics of the Charmed Baryon $Λ_{c}^{+}$ in $e^{+} e^{-}$ Annihilations near Threshold

BESIII Collaboration, M. Ablikim, M. N. Achasov +700

The study of the charmed baryons is crucial for investigating the strong and weak interactions in the standard model and for gaining insights into the internal structure of baryons…

Improved Measurements of $D^{+} \to η e^{+} ν_{e}$ and $D^{+} \to η μ^{+} ν_{μ}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +677

Using 20.3 fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected at the center-of-mass energy of 3.773 GeV with the BESIII detector, we measure the branching fractions of $D^{+} \to η e^{+} ν_{e}$ …

Search for $Δ S = 2$ nonleptonic hyperon decays $Ω^{-} \to Σ^{0} π^{-}$ and $Ω^{-} \to n K^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +644

Using $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ events collected by the BESIII detector at the center-of-mass energy of $s = 3.686$ GeV, we search for the first time for tw…

Observation of $ψ (3686) \to Ω^{-} K^{+} Ξ ˉ^{0}$ +c.c

BESIII Collaboration, M. Ablikim, M. N. Achasov +640

Using $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ events collected with the BESIII detector at BEPCII, the decay of $ψ (3686) \to Ω^{-} K^{+} Ξ ˉ^{0} + c . c .$ is observed for the first tim…

Observation of $χ_{c J} \to 3 (K^{+} K^{-})$

BESIII Collaboration, M. Ablikim, M. N. Achasov +642

By analyzing $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ events collected with the BESIII detector operating at the BEPCII collider, the decay processes $χ_{c J} \to 3 (K^{+} K^{-})$ ( $J = 0, 1, 2$ )…
