Abstract: (arXiv)

We report a measurement of the average

B

-hadron lifetime using data collected with the SLD detector at the SLC in 1993. An inclusive analysis selected three-dimensional vertices with

B

-hadron lifetime information in a sample of 50k

Z^{0}

decays. A lifetime of

1.564\pm0.030\,(\rm stat)\pm 0.037\,(\rm syst)

~ps was extracted from the decay length distribution of these vertices using a binned maximum-likelihood method.
