Observation of the charmonium decay $η_{c} \to γ γ$ in $J / ψ \to γ η_{c}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +662

Using $(2712.4 \pm 14.3) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector at the BEPCII collider, the decay $η_{c} \to γ γ$ in $J / ψ \to γ η_{c}$ is observed. We determine the p…

Measurement of the Decay $Ξ^{0} \to Λ γ$ with Entangled $Ξ^{0} Ξ ˉ^{0}$ Pairs

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

In this Letter, a systematic study of the weak radiative hyperon decay $Ξ^{0} \to Λ γ$ at an electron-positron collider using entangled $Ξ^{0} Ξ ˉ^{0}$ pair events is presented. The…

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…
