Abstract

The measurement of the average lifetime of B hadrons using inclusively reconstructed secondary vertices has been updated using both an improved processing of previous data and additional statistics from new data. This has reduced the statistical and systematic uncertainties and gives tau(B) = 1.582+/-0.011 (stat.)+/-0.027 (syst.) ps. Combining this result with the previous result based on charged particle impact parameter distributions yields tau(B) = 1.575+/-0.010 (stat.)+/-0.026 (syst.) ps.
