First QCD results were obtained from the CDF experiment using Run
II data are reported. The Run II physics program at the Tevatron started in
the spring of 2001, with protons and antiprotons colliding at an energy of
sqrt s = 1.96 TeV. The size of the data sample already compares to that of
Run I. Results presented here include the measurement of the inclusive jet
cross section, a search for new particles decaying to dijets, and a study of
diffractive dijet events.
