Abstract
We report a measurement of the lifetime of the Λ[superscript 0][subscript b] baryon in decays to the Λ[superscript +][superscript c]π[superscript −] final state in a sample corresponding to 1.1 fb[superscript −1] collected in p[¯ over p] collisions at √s=1.96 TeV by the CDF II detector at the Tevatron collider. Using a sample of about 3000 fully reconstructed Λ[superscript 0][subscript b] events we measure τ(Λ[superscript 0][subscript b]) =1.401±0.046(stat)±0.035(syst) ps (corresponding to cτ(Λ[superscript 0][subscript b])=420.1±13.7(stat)±10.6(syst) μm, where c is the speed of light). The ratio of this result and the world average B[superscript 0] lifetime yields τ(Λ[superscript 0][subscript b])/τ(B[superscript 0])=0.918±0.038 (stat) and (syst), in good agreement with recent theoretical predictions. © 2010 American Physical Society
