Abstract

We combine the D0 measurement of the width difference between the light and heavy Bs0 mass eigenstates and of the CP-violating mixing phase determined from the time-dependent angular distributions in the Bs0\ensuremath→J/\ensuremathψ\ensuremathφ decays along with the charge asymmetry in semileptonic decays also measured with the D0 detector. With the additional constraint from the world average of the flavor-specific Bs0 lifetime, we obtain \ensuremathΔ\ensuremathΓs\ensuremath≡(\ensuremathΓL\ensuremath-\ensuremathΓH)=0.13\ifmmode±\else\textpm\fi0.09 ps^\ensuremath-1 and |\ensuremathφs|=0.70_\ensuremath-0.47+0.39 or \ensuremathΔ\ensuremathΓs=\ensuremath-0.13\ifmmode±\else\textpm\fi0.09 ps^\ensuremath-1 and |\ensuremathφs|=2.44_\ensuremath-0.39+0.47. The data sample corresponds to an integrated luminosity of 1.1 fb^\ensuremath-1 accumulated with the D0 detector at the Fermilab Tevatron Collider.
