| dc.description | This paper summarises the recent results of the Run IIa D0 experiment at the Tevatron Collider at Fermilab on the observable parameters of the $B_{s}$ meson. A measurement of the branching fraction $B_s->D_s^{(*)}D_s^{(*)}$ is reported, which provides an estimate of the width difference $ΔΓ_{s}^{CP}/ΔΓ_{s}$. Through the decay $B_{s} \to J/ψϕ$ the width difference $ΔΓ_{s}$ is extracted, and for the first time a constraint is set on the CP-violating phase $ϕ_{s}$, although a four-fold ambiguity remains. This result is combined with other D0 measurements to yield $ΔΓ_{s}=0.13\pm0.09 {\rm ps^{-1}}$, $ϕ_{s} = -0.70^{+0.47}_{-0.39}$. | |
