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…

Observation of $χ_{c 0} \to Σ^{+} Σ ˉ^{-} η$ and evidence for $χ_{c 1, 2} \to Σ^{+} Σ ˉ^{-} η$

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, the decay $χ_{c 0} \to Σ^{+} Σ ˉ^{-} η$ is observed for the first time with a statistical sign…

Search for $Λ$ - $Λ ˉ$ oscillation in $J / ψ \to Λ Λ ˉ$ decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +643

Using $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ decays collected by the BESIII detector at the BEPCII collider, we search for baryon number violation via $Λ - Λ ˉ$ oscillation in the decay…

Study of the decays $χ_{c J} \to Λ Λ ˉ ω$

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

Using $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ events collected with the BESIII detector, we present the first observation of the decays $χ_{c J} \to Λ Λ ˉ ω$ , where $J = 0, 1, 2$ , with…
