The inclusive jet and dijet mass cross sections are compared to NLO pQCD calculations and to Run I results. The production rates and kinematic properties of W + jets production processes are compared to ``enhanced'' LO theoretical predictions. Non-perturbative ``soft'' interactions leading to the underlying event are studied and compared to QCD Monte Carlo phenomenological models.Presented at 18th Les Rencontres De Physique De La Vallee D'Aoste: Results and Perspectives in Particle Physics, La Thuile, Aosta Valley, Italy, Feb. 29 - March 6, 2004High Energy Physics - Experimenttext
