$t\bar{t}$\ Cross-section Measurement into Multi-Jet Final States

We present a $t\bar{t}$\ production cross section measurement in the multi-jet final state channel from collisions of protons and anti-protons at 1.96 TeV at the Collider Detector at Fermilab (CDF). We study events, selected using optimized kinematical criteria, that contain jets that are identified in the Silicon Vertex Detector as originating from b-quarks. Contributions to the measurement from events with hadronically decaying taus are also discussed.
