Abstract

A high statistics measurement of the Lambda(c)(+) lifetime from the Fermilab fixed-target FOCUS photoproduction experiment is presented. We describe the analysis technique with particular attention to the determination of the systematic uncertainty. The measured value of 204.6+/-3.4 (stat )+/-2.5 (syst) fs from 8034+/-122 Lambda(c)(+) -->pK(-)pi(+) decays represents a significant improvement over the present world average.
