Measurement of the Lambda+(c) lifetime

A precise measurement of the [Lambda][sub [ital c]][sup +] lifetime using approximately 1340 fully reconstructed [Lambda][sub [ital c]][sup +][r arrow][ital pK][sup [minus]][pi][sup +] and charge conjugate decays is presented. The data were accumulated by the Fermilab high energy photoproduction experiment E687. The lifetime of the [Lambda][sub [ital c]][sup +] is measured to be 0.215[plus minus]0.016[plus minus]0.008 ps.
