Precision Study of $η^{'} \to γ π^{+} π^{-}$ Decay Dynamics

BESIII Collaboration, M. Ablikim, M. N. Achasov +431

Using a low background data sample of $9.7 \times 1 0^{5}$ $J ψ \to γ η^{'}$ , $η^{'} \to γ π^{+} π^{-}$ events, which are 2 orders of magnitude larger than those from the pr…

Branching fraction measurement of $J / ψ \to K_{S} K_{L}$ and search for $J / ψ \to K_{S} K_{S}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +441

Using a sample of $1.31 \times 1 0^{9}$ $J / ψ$ events collected with the BESIII detector at the BEPCII collider, we study the decays of $J / ψ \to K_{S} K_{L}$ and $K_{S} K_{S}$ . The br…

Improved measurements of two-photon widths of the $χ_{c J}$ states and helicity analysis for $χ_{c 2} \to γ γ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +435

Based on $448.1 \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector, the decays $ψ (3686) \to γ χ_{c J}, χ_{c J} \to γ γ (J = 0, 1, 2)$ are studied. The decay branching fractio…
