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…

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…

Measurement of the $e^{+} e^{-} \to π^{+} π^{-} J / ψ$ cross section in the vicinity of 3.872 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +566

We report a measurement of the cross section for the process $e^{+} e^{-} \to π^{+} π^{-} J / ψ$ around the $X (3872)$ mass in search for the direct formation of $e^{+} e^{-} \to X (3872)$ through the tw…
