Measurement of the Λb0 lifetime in Λb0→Λc+π - decays in pp̄ collisions at √s=1.96TeV

We report a measurement of the lifetime of the Λb0 baryon in decays to the Λc+π- final state in a sample corresponding to 1.1fb-1 collected in pp̄ collisions at √s=1.96TeV by the CDF II detector at the Tevatron collider. Using a sample of about 3000 fully reconstructed Λb0 events we measure τ(Λb0)=1...
