Abstract

We present the latest B hadron lifetimes, B⁰_s mixing, and D⁰ mixing measurements using up to 3.0 fb^-1 of data collected by CDF and D0 experiments at Fermilab. The B⁰_s lifetime is measured from both J/ψϕ (CP admixture) and flavor specific channels, and the B_c lifetime is obtained from semileptonic channels. Following the B⁰_s oscillation frequency measurement at CDF in 2006, the D0 collaboration now observes B⁰_s oscillation at a significance of about 3σ. Since the first D⁰ mixing evidence established at B factories in 2007, CDF has observed D⁰ mixing at a significance of about 4σ level, the first time from hadron collider.
