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 $e^{+} e^{-} \to Λ Λ ˉ$ cross section from threshold to 3.00 GeV using events with initial-state radiation

BESIII Collaboration, M. Ablikim, M. N. Achasov +600

Using initial-state radiation events from a total integrated luminosity of 11.957 fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected at center-of-mass energies between 3.773 and 4.258…
