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…

Study of the decays $χ_{c J} \to Λ Λ ˉ ϕ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +643

Based on $(2712.4 \pm 14.3) \times 1 0^{6}$ $e^{+} e^{-} \to ψ (3686)$ events collected with the BESIII detector operating at the BEPCII collider, we report the first evidence of $χ_{c…

Search for the radiative transition $χ_{c 1} (3872) \to γ ψ_{2} (3823)$

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

Using 9.0 $f b^{- 1}$ of $e^{+} e^{-}$ collision data collected at center-of-mass energies from 4.178 to 4.278 GeV with the BESIII detector at the BEPCII collider, we perform the firs…
