Bs Mixing and Lifetime Difference at CDF
  The measurements of the \Bs mixing parameter which describes the difference in width (the inverse of the lifetime) between the \Bs heavy and light states are described. These measurements include direct measurement of $\Delta \Gamma_s$ and $\Gamma_s$ by resolving CP eigenstates by angular analysis and measurements in which the proportion of CP even and odd is known.
