摘要：

Measurements of the lifetimes of the LAMBDA(c)+ decaying into pK-pi+ and of the D(s)+ decaying into phi-pi+ are presented. The data were accumulated in the Fermilab Wide-Band photoproduction experiment E687. The lifetimes of the LAMBDA(c)+ and the D(s)+ are measured to be (0.20 +/- 0.03 +/- 0.03) X 10(-12)S and (0.50 +/- 0.06 +/- 0.03) X 10(-12)S respectively.
