Jets are widely used as probes of the fundamental parton collisions in Quantum Chromodynamics. Jets, which are believed to represent the energies and directions of the emerging partons, are viewed by the experimenter as collimated distributions of hadrons. The momenta and angles of these hadrons must be combined to form the parent jet. Because of measurement resolutions and the unavoidable presence of backgrounds, a jet is thus dependent on the precise nature of the combination algorithm. A Kt type of jet algorithm for use in hadron collisions has been introduced at D0 and we have investigated its dependence on the energy and pseudorapidity scales of the D0 detector.
