Abstract
From an analysis of the flavor-tagged decay Bs0→J/ψφ we obtain the width difference between the Bs0 light and heavy mass eigenstates, ΔΓs=0.19±0.07(stat)-0.01+0.02(syst) ps-1, and the CP-violating phase, φs=-0.57-0.30+0.24(stat)-0.02+0.08(syst). The allowed 90% CL intervals of ΔΓs and φs are 0.06<ΔΓs<0.30 ps-1 and -1.20<φs<0.06, respectively. The data sample corresponds to an integrated luminosity of 2.8 fb-1 accumulated with the D0 detector at the Fermilab Tevatron collider.
