We report an updated measurement of the CP-violating phase, ΦsJ/ψΦ, and the decay-width difference for the two mass eigenstates, ΔΓs, from the flavor-tagged decay B0s→J/ψΦ. The data sample corresponds to an integrated luminosity of 8.0 fb⁻¹ accumulated with the D0 detector using pp̄ collisions at √s=1.96 TeV produced at the Fermilab Tevatron collider. The 68% Bayesian credibility intervals, including systematic uncertainties, are ΔΓs=0.163+0.065₋0.064 ps⁻¹ and ΦsJ/ψΦ=₋0.55+0.38₋0.36. The p-value for the Standard Model point is 29.8%.
