Abstract: (Springer)

Using approximately 4 million hadronic Z decays recorded with the aleph detector from 1991 through 1995, the lifetime of the b baryon is measured with three independent methods. From the impact parame

electron positron: colliding beams
electron positron: annihilation
Z0: electroproduction
Z0: hadronic decay
bottom: pair production
Lambda/b0: semileptonic decay
Lambda/b0: branching ratio
Lambda/b0: lifetime
final state: (Lambda lepton-)
final state: (Lambda lepton+ lepton-)
