Abstract
A high statistics measurement of the lifetime from the Fermilab fixed-target FOCUS photoproduction experiment is presented. We describe the analysis of the two decay modes, and , used for the measurement. The measured lifetime is using and decays. This is a significant improvement over the present world average.
