Observation of the Electromagnetic Dalitz Transition $h_{c} \to e^{+} e^{-} η_{c}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +504

Using $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ decays and data samples of $e^{+} e^{-}$ collisions with $s$ from 4.130 to 4.780~GeV collected with the BESIII detector, we report the…

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…

Search for di-photon decays of an axion-like particle in radiative $J / ψ$ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +614

We search for the di-photon decay of a light pseudoscalar axion-like particle, $a$ , in radiative $J / ψ$ decays, using 10 billion $J / ψ$ events collected with the BESIII detector. We…
