Study of the decay ψ(3686) \to Σ^{0}\barΣ^{0}ϕ

BESIII Collaboration, M. Ablikim, M. N. Achasov +649

Using $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ events collected with the BESIII detector operating at the BEPCII collider, the decay $ψ (3686) \to Σ^{0} Σ ˉ^{0} ϕ$ is observed for the…

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…
