Measurement of CP Asymmetry Parameters and Polarization Correlations in $Ω^{-} Ω ˉ^{+}$ Pairs

BESIII Collaboration, M. Ablikim, M. N. Achasov +773

Using $(2.71 \pm 0.01) \times 1 0^{9}$ $ψ (3686)$ events collected with the BESIII detector, a joint full angular distribution analysis is carried out for the process $ψ(3686) \to Ω^-(…
