First measurement of the cross sections for $e^{+} e^{-} \to K^{0} K^{-} π^{+} J / ψ + c . c .$ at $s$ from 4.396 to 4.951 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +701

Using $e^{+} e^{-}$ collision data at 19 center-of-mass energies ranging from $4.396$ to $4.951 GeV$ corresponding to a total integrated luminosity of $8.86 fb^{- 1}$ coll…

Observation of the electromagnetic radiative decays of the \boldmath{ $Λ (1520)$ } and \boldmath{ $Λ (1670)$ } to \boldmath{ $γ Σ^{0}$ }

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

Using $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, we report the first observation of the electromagnetic radiative decays of the $Λ (1520)$ and $Λ(167…

Search for the rare decay $J / ψ \to γ D^{0} + c . c .$ at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +650

Using $(10087 \pm 44) \times 1 0^{6} J / ψ$ events collected with the BESIII detector, we search for the rare decay $J / ψ \to γ D^{0} + c . c .$ for the first time. No obvious signal is observed and t…

Precision measurement of the branching fraction of \boldmath $J / ψ \to K^{+} K^{-}$ via $ψ (2 S) \to π^{+} π^{-} J / ψ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +615

Using a sample of $448.1 \times 1 0^{6}$ $ψ (2 S)$ events collected with the BESIII detector, we perform a study of the decay $J / ψ \to K^{+} K^{-}$ via $ψ (2 S) \to π^{+} π^{-} J / ψ$ . T…
