QCD and Hadron Physics at CDF

Results to be reported below are mostly based on the Run II data. To remind, CDF has undergone a number of major upgrades for the Run II, with a good fraction of the old CDF scrapped and replaced with brand new apparatus, designed to work at higher luminosity, providing better performance, and adding new capabilities. The CDF-II tracker can do the full track reconstruction, including 3D-vertex, in a much wider range |η| ≤2, the calorimeters are hermetic up to |η|=5.1, the muon system covers the |η|-range up to 1.5. Another important upgrade is the added capability to trigger on the displaced vertices (b-tagging) and tracks with pT >1.5 GeV/c. Tevatron center of mass energy in Run II is 1.96 TeV vs 1.8 TeV of Run I. As of May 2003, CDF has accumulated data corresponding to an integrated luminosity of about 130 pb−1. However, many results to be presented will be based on somewhat smaller statistics.
