Search for lepton number violating decays of $D_{s}^{+} \to h^{-} h^{0} e^{+} e^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +655

Based on 7.33 fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected by the BESIII detector operating at the BEPCII collider at center-of-mass energies from 4.128 to 4.226 GeV, a search fo…

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…

Model-independent determination of the strong-phase difference between $D^{0}$ and $D ˉ^{0} \to π^{+} π^{-} π^{+} π^{-}$ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +652

Measurements of the strong-phase difference between $D^{0}$ and $D ˉ^{0} \to π^{+} π^{-} π^{+} π^{-}$ are performed in bins of phase space. The study exploits a sample of quantum-correlated $D\…

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…
