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

Using $(2.71 \pm 0.01) \times 10^9$ $ψ(3686)$ events collected with the BESIII detector, a joint full angular distribution analysis is carried out for the process $ψ(3686) \to Ω^-(\toΛK^-) \, \barΩ^{+}(\to \barΛK^+)$. The first simultaneous measurement of the weak decay parameters $ϕ_{Ω^{-}}$ and $ϕ
