We report the results of a precise measurement of the D_s meson lifetime based on 1662 ± 56 fully reconstructed D_s → φπ decays, from the charm hadroproduction experiment E791 at Fermilab. Using an unbinned maximum likelihood fit, we measure the D_s lifetime to be 0.518 ± 0.014 ± 0.007 ps. The ratio of the measured D_s lifetime to the world average D⁰ lifetime [1] is 1.25 ± 0.04. This result differs from unity by six standard deviations, indicating significantly different lifetimes for the D_s and the D⁰.
