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 -> pKpi decays represents a significant improvement over the present world average.
