Observation of $η^{'} \to π^{+} π^{-} μ^{+} μ^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +486

Using $(1310.6 \pm 7.0) \times 1 0^{6} J / ψ$ events acquired with the BESIII detector at the BEPCII storage rings, the decay $η^{'} \to π^{+} π^{-} μ^{+} μ^{-}$ is observed for the fir…

Inclusive charged and neutral particle multiplicity distributions in $χ_{c J}$ and $J / ψ$ decays

BESIII collaboration, M. Ablikim, M. N. Achasov +474

Using a sample of 106 million $ψ (3686)$ decays, $ψ (3686) \to γ χ_{c J} (J = 0, 1, 2)$ and $ψ (3686) \to γ χ_{c J}, χ_{c J} \to γ J / ψ$ $(J = 1, 2)$ events are utilized to study inclusive $…

Measurement of higher-order multipole amplitudes in $ψ (3686) \to γ χ_{c 1, 2}$ with $χ_{c 1, 2} \to γ J / ψ$ and search for the transition $η_{c} (2 S) \to γ J / ψ$

M. Ablikim, M. N. Achasov, X. C. Ai +424

Using 106~million $ψ (3686)$ events collected with the BESIII detector, we measure multipole amplitudes for the decay $ψ (3686) \to γ χ_{c 1, 2} \to γ γ J / ψ$ beyond the dominant elect…
