$B_s$ Mixing Results for Hadronic and Semileptonic Decays at CDF

We report preliminary results for $B_s$ oscillation from CDF Run II at
the Fermilab Tevatron collider.  The analysis combines hadronic and
semileptonic channels from 1 fb$^{-1}$ of data collected by a
displaced-track trigger which uses CDF's precision silicon tracking.
New techniques in flavor tagging and event reconstruction and the
addition of new decay modes yield a significant improvement in mixing
sensitivity as compared to earlier CDF results.
