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…

Improved measurement of the branching fraction of $D_{s}^{+} \to μ^{+} ν_{μ}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +608

Using $e^{+} e^{-}$ collision data with an integrated luminosity of $7.33 fb^{- 1}$ collected at center-of-mass energies between 4.128 and 4.226 GeV with the BESIII detector ope…
