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…

Search for the radiative decays $D^{0} \to γ K ˉ_{1} (1270)^{0}$ and $D^{+} \to γ K_{1} (1270)^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +680

A search for the radiative decays $D^{0} \to γ K ˉ_{1} (1270)^{0}$ and $D^{+} \to γ K_{1} (1270)^{+}$ is conducted using $20.3 fb^{- 1}$ of $e^{+} e^{-}$ annihilation data collected at the cen…
