    Abstract
    We report an updated measurement of the CP-violating phase, ϕJ/ψϕs, 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 pp¯ 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 ϕJ/ψϕs=−0.55+0.38−0.36. The p-value for the Standard Model point is 29.8%.
