Abstract
We report a measurement of the Bs0 lifetime in the semileptonic decay channel Bs0→Ds-μ+ν X (and its charge conjugate), using approximately 0.4 fb-1 of data collected with the D∅ detector during 2002-2004. Using 5176 reconstructed Ds-μ+ signal events, we have measured the Bs0 lifetime to be t(Bs0)=1.398±0.044(stat)-0.025+0.028(syst) ps. This is the most precise measurement of the Bs0 lifetime to date.
