Measurement Of The Lambda(c)+ And D(s)+ Lifetimes
by P.L. Frabetti et al.
Abstract. Measurements of the lifetimes of the Lambda(c) decaying into p K pi and of the D(s) decaying into phi pi are presented. The data were accumulated in the Fermilab Wide-Band photoproduction experiment E-687. The lifetimes of the Lambda(c) and the D(s) are measured to be 0.20 +- 0.03 +- 0.03 ps and 0.50 +- 0.06 +- 0.03 ps respectively.

More information on these lifetimes can be found in PRL 70 (1993) 1755 and PRL 71 (1993) 827.
