We report a measurement of the average B hadron lifetime using data collected with the SLD detector at the SLAG Linear Collider in 1993. An inclusive analysis selected three-dimensional vertices with B hadron lifetime information in a sample of 50 x 10(3) Z(0) decays. A lifetime of 1.564 +/- 0.030(stat) +/- 0.036(syst) ps was extracted from the decay length distribution of these vertices using a binned maximum likelihood method.

Abstract
We report a measurement of the average B hadron lifetime using data collected with the SLD detector at the SLAG Linear Collider in 1993. An inclusive analysis selected three-dimensional vertices with B hadron lifetime information in a sample of 50 x 10(3) Z(0) decays. A lifetime of 1.564 +/- 0.030(stat) +/- 0.036(syst) ps was extracted from the decay length distribution of these vertices using a binned maximum likelihood method.File in questo prodotto:
