Measurement of the CP-violating phase φsJ/ψφ using the flavor-tagged decay Bs0 → J/ψφ in 8 fb-1 of p(bar p) collisions
Description
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 Bs0 → J/ψφ. The data sample corresponds to an integrated luminosity of 8.0 fb-1 accumulated with the D0 detector using p(bar p) collisions at √s = 1.96 TeV produced at the Fermilab Tevatron collider. The 68% Bayesian credibility intervals, including systematic uncertainties, are ΔΓs = 0.163-0.064+0.065 ps-1 and φsJ/ψφ = -0.55-0.36+0.38. The p-value for the Standard Model point is 29.8%.
