I. INTRODUCTION The theory of quantum chromodynamics (QCD) [1] is currently the best description of the fundamental strong force. This theory describes the color interaction between quarks as being mediated by gluons, which are the vector bosons of the strong force. It has been successfully tested in collisions between e $^{+}$e − [2], ep [3], pp [4], and pp [5]. One of the basic properties of QCD is that its coupling strength α$_{s}$ decreases with the energy of the interaction and that, at sufficiently high energies, QCD calculations can be performed using perturbation theory in powers of α$_{s}$ [6]. Currently, these perturbartive QCD (pQCD) calculations are available at a next-to-leading order (NLO) for many processes and, in some cases, at next-to-next-to-leading order (NNLO) approximation. Leading order (LO) calculations, supplemented with parton shower calculations [7], are used in several Monte Carlo event generators [8, 9]. In addition, matrix element generators which match NLO calculations of rates for QCD processes with a parton shower Monte Carlo event generator are also available [10], but only a limited number of processes have been implemented. The pQCD calculations result in a small number of partons in the final state, while experimenters observe “jets” of particles. These jets retain the kinematic properties (energy and momentum) of the parent partons (quarks or gluons). In order to facilitate comparison between data and calculation, jet finding algorithms have been devised that are insensitive to the difficult-to-calculate low energy phenomena that govern the transition from low- multiplicity partons to high-multiplicity particle final states. There are several jet finding algorithms and the details of the measurements are sensitive to that choice. While events in which jets are created are used for a detailed understanding of the strong force, it is also possible that such events could also reveal new physical phenomena, including quark substructure (compositeness), extra spatial dimensions and new particles which decay into jets. Because of their high energy, jets can probe very small distances. At the Tevatron, the highest p$_{T}$ jets can probe distances down to O (10 − $^{17}$) cm. In 2001, the Fermilab Tevatron pp collider commenced its Run II, with a collision energy of 1.96 TeV. This energy is higher than the 1992 − 1996 Run I energy of 1.8 TeV. Even this relatively small increase in energy leads to a substantial increase in jet production with large transverse momentum, p$_{T}$ , by about a factor of three at p$_{T}$ = 500 GeV /c . The beam intensity is much higher than Run I due to the addition of the Main Injector and the Recycler Ring 2
