B-Hadron Lifetimes and ΔΓ at the Tevatron
R. J. Lipton
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 Bs CP eigenstates, ΔΓ/ Γ , in Bs decays to J/ψϕ is also presented.
