A Measurement Of The Lambda(c)+ Lifetime
by P.L. Frabetti et al.
Abstract. A precise measurement of the Lambda(c)+ lifetime using approximately 1340 fully reconstructed Lambda(c)+ --> pK-pi+ and charge conjugate decays is presented. The data were accumulated by the Fermilab high energy photoproduction experiment E687. The lifetime of the Lambda(c)+ is measured to be 0.215+-0.016+-0.008 ps.
