Contribution

It provides new measurements of jet cross sections at different energies and analyzes three-jet event properties, extending previous experimental data and testing QCD predictions.

Findings

Inclusive one jet cross section measured at 1.96 TeV

Properties of three-jet events studied at 1.8 TeV

Results generally agree with NLO QCD predictions

Abstract

Recent measurements of jet and multijet production cross sections from ppbar collisions recorded with the Collider Detector at Fermilab (CDF) are summarized. First Run II results of the inclusive one jet cross section at sqrt(s) = 1.96 TeV as well as prospects for future extensions of this measurement are presented. We also studied the properties of three-jet events in Run Ib data at sqrt(s) = 1.8 TeV. All results are compared to predictions of Quantum Chromodynamics at next-to-leading order perturbation theory.
