z-SCALING AND JET PRODUCTION IN HADRON–HADRON COLLISIONS AT HIGH ENERGIES

Inclusive jet production in [Formula: see text] and pp collisions at high energies in the framework of the concept of z-scaling is studied. The available experimental data on the cross-section of jet production obtained by the UA1, UA2, CDF and D0 Collaborations are used for analysis. The scaling function ψ(z) is expressed via inclusive cross-section Ed3σ/dq3 and jet multiplicity density ρ(s,η). The properties of z-scaling, the energy and angular independence of ψ(z) and the power behavior, ψ(z)~z-α, of jet and dijet production were found. Based on the properties of z-scaling, the dependence of the cross-section of jets produced in [Formula: see text] and pp collisions on transverse momentum q⊥ over the central range is predicted. The obtained results can be of interest for future experiments planned at RHIC, LHC, HERA and Tevatron to search for new phenomena in hadron–hadron, hadron–nucleus and nucleus–nucleus collisions.
