| dc.description | We report a measurement of the $B^0_{s}$ lifetime in the semileptonic decay channel $B^0_{s}\to D^-_s μ^{+}νX$ (and its charge conjugate), using approximately 0.4 fb$^{-1}$ of data collected with the D0 detector during 2002 -- 2004. We have reconstructed 5176 $D^-_s μ^{+}$ signal events, where the $D_s^-$ is identified via the decay $D_s^-\to ϕπ^-$, followed by $ϕ\to K^+ K^-$. Using these events, we have measured the $B^0_s$ lifetime to be $τ(B^0_{s}) = 1.398 \pm 0.044$ $({stat}) ^{+0.028}_{-0.025}$ $({syst}) {ps}$. This is the most precise measurement of the $B_s^0$ lifetime to date. | |
