Description

We present the CDF results using 1.0 fb-1 of data on the mixing frequency measurement in the Bs0 system and the lifetime measurements of several B hadrons. We obtain δms = 17.77 ± 0.1 ± 0.07 ps-1 and cτ(Λb) = 473.8 ± 23.1 ± 3.5/μm. The later one is more than 3σ above the world average, but in reasonable agreement with HQE calculations
