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

摘要

Inclusive jet production in (p) over bar p 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 DO Collaborations are used for analysis. The scaling function 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 of z-scaling, the dependence of the cross-section of jets produced in (p) over bar p and pp collisions on transverse momentum q perpendicular to 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.
