Abstract

A high statistics measurement of the

Λ_{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 \pm 3.4 (stat) \pm 2.5 (syst) fs

from

8034 \pm 122 Λ_{c}^{+} \to {pK}^{-} π^{+}

decays represents a significant improvement over the present world average.
