Observation of an Altered $a_{0} (980)$ Line-shape in $D^{+} \to π^{+} η η$ due to the Triangle Loop Rescattering Effect

BESIII Collaboration, M. Ablikim, M. N. Achasov +697

Using 20.3~ $fb^{- 1}$ of $e^{+} e^{-}$ collision data taken with the BESIII detector at the center-of-mass energy 3.773~GeV, we report the first amplitude analysis of the hadro…

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…
