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…
