| dc.description | From an analysis of the flavor-tagged decay \bsdec we obtain the width difference between the $B_s^0$ light and heavy mass eigenstates, $ΔΓ_s \equiv Γ_L - Γ_H = 0.19 \pm 0.07 {\rm (stat)}\thinspace ^{+0.02}_{-0.01} {\rm (syst)}$ ps$^{-1}$, and the CP-violating phase, $ϕ_{s} =-0.57 ^{+0.24}_{-0.30} {\rm (stat)}\thinspace ^{+0.07}_{-0.02} {\rm (syst)}$. The allowed 90% C.L. intervals of $ΔΓ_s$ and $ϕ_s$ are $0.06 <ΔΓ_s <0.30$ ps$^{-1}$ and $-1.20 <ϕ_s < 0.06$, respectively. The data sample corresponds to an integrated luminosity of 2.8 fb$^{-1}$ accumulated with the D0 detector at the Fermilab Tevatron collider. | |
