摘要：

A high statistics measurement of the D-s(+) lifetime from the Fermilab fixed-target FOCUS photoproduction experiment is presented. We describe the analysis of the two decay modes, D-s(+)->phi(1020)pi(+) and D-s(+)->(K) over bar*(892)K-0(+), used for the measurement. The measured lifetime is 507.4 +/- 5.5(stat)+/- 5.1(syst) fs using 8961 +/- 105 D-s(+)->phi(1020)pi(+) and 4680 +/- 90 D-s(+)->(K) over bar*(892)K-0(+) decays. This is a significant improvement over the present world average.
