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…

Evidence for Two Excited $Ω^{-}$ Hyperons

BESIII Collaboration, M. Ablikim, M. N. Achasov +655

Using $e^{+} e^{-}$ collision data corresponding to an integrated luminosity of 19,fb $^{- 1}$ collected by the BESIII detector at center-of-mass energies ranging from 4.13 to 4.70,GeV, w…
