摘要：
A precise measurement of the D(s)+/- meson lifetime is reported. The data were accumulated by the high energy photoproduction experiment E687 at Fermilab in the 1990-1991 fixed target run. The measurement has been done using 900 fully reconstructed D(s)+/- --> phipi+/- decays. The lifetime of the D(s)+/- meson is measured to be 0.475 +/- 0.020 +/- 0.007 ps.
