Abstract

We present new results on the lifetimes and widths of B hadrons based on 300-450 pb^-1 of data collected by CDF and DØat the Fermilab Tevatron. Lifetimes were measured in semileptonic decays as well as fully reconstructed hadronic modes. A new measurement of the width difference between B_s CP eigenstates, ΔΓ/ Γ , in B_s decays to J/ψϕ is also presented.
