Amplitude Analysis of the Isospin-Violating Decay $J / ψ \to γ η π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +759

Using $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, we perform the first amplitude analysis of the process $J / ψ \to γ η π^{0}$ . The decay is dominated b…

Resonant Parameters of Vector Charmonium-like States above 4.4 GeV

Chunhua Li, Wanting Liu, Linfa Tang +1

We analysis the $s$ -dependent line shapes of the $e^{+} e^{-} \to D_{s}^{+} D_{s 1}^{*-} (2536)$ , $D_{s}^{+} D_{s 2}^{*-} (2573)$ , $ϕ χ_{c 1, 2}$ , $K^{+} K^{-} J / ψ$ , $K_{S}^{0} K_{S}^{0} J / ψ$ , and $K^+K^-ψ(…
