Observation of $η_{c} (2 S) \to K^{+} K^{-} η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +645

By analyzing $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ events accumulated with the BESIII detector, the decay $η_{c} (2 S) \to K^{+} K^{-} η$ is observed for the first time with a sig…

Measurement of the Branching Fraction for the Decay $ψ (3686) \to ϕ K_{S}^{0} K_{S}^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +592

Based on $(448.1 \pm 2.9) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector operating at the BEPCII collider, the decay $ψ (3686) \to ϕ K_{S}^{0} K_{S}^{0}$ is…
