| الوصف: |
The average lifetime of baryons containing a b quark has been measured with the OPAL detector using data collected between 1990 and 1992. Semileptonically decaying b-flavoured baryons which produce a Λ are identified through the charge correlation of the Λ and lepton. The decay point of the b baryon is estimated by the Λ-lepton vertex, and the observed distribution of decay lengths is fitted to determine the average lifetime. In the data sample consisting of 261 right-sign and 104 wrong-sign Λ-lepton charge combinations, the average b baryon lifetime is found to be τ = 1.05 ± 0.08 ps, where the first error is statistical and the second systematic. |
