z-Scaling and jet production in hadron-hadron collisions at high energies

Inclusive jet production in (p) over bar p and pp collisions at high energi es in the framework of the concept of z-scaling is studied. The available e xperimental data on the cross-section of jet production obtained by the UA1 , UA2, CDF and DO Collaborations are used for analysis. The scaling functio n psi(z) is expressed via inclusive cross-section Ed(3)sigma/dq(3) and jet multiplicity density rho(s,eta) The properties of z-scaling, the energy and angular independence of psi(z) and the power behavior, psi(z) similar to z (-alpha), of jet and dijet production were found. Based on the properties o f z-scaling, the dependence of the cross-section of jets produced in (p) ov er bar p and pp collisions on transverse momentum q perpendicular to over t he central range is predicted. The obtained results can be of interest for future experiments planned at RHIC, LHC, HERA and Tevatron to search for ne w phenomena in hadron-hadron, hadron-nucleus and nucleus-nucleus collisions .
