%X We present a measurement of the ratio of the (B) over bar (0)(s) meson lifetime, in the flavor-specific decay to D-s(+)pi(-), to that of the (B) over bar (0) meson. The pp collision data used correspond to an integrated luminosity of 1 fb(-1), collected with the LHCb detector, at a center-of-mass energy of 7 TeV. Combining our measured value of 1.010 +/- 0.010 +/- 0.008 for this ratio with the known (B) over bar (0) lifetime, we determine the flavor-specific (B) over bar (0)(s) lifetime to be tau((B) over bar (0)(s) ) = 1.535 +/- 0.015 +/- 0.014 ps, where the uncertainties are statistical and systematic, respectively. This is the most precise measurement to date, and is consistent with previous measurements and theoretical predictions.
