Abstract
We report a measurement of the lifetime of the Λb0 baryon in decays to the Λc+π- final state in a sample corresponding to 1.1  fb-1 collected in pp&#773; collisions at √s=1.96  TeV by the CDF II detector at the Tevatron collider. Using a sample of about 3000 fully reconstructed Λb0 events we measure τ(Λb0)=1.401±0.046(stat)±0.035(syst)  ps (corresponding to cτ(Λb0)=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 B0 lifetime yields τ(Λb0)/τ(B0)=0.918±0.038 (stat) and (syst), in good agreement with recent theoretical predictions.
