Generalized z-scaling for charged hadrons and jets

Generalization of z-scaling observed in the inclusive high-p_T-charged hadron and jet production is proposed. Scaling function ψ(z) describing both charged hadrons and jets produced in proton-(anti)proton colisions for various multiplicity densities and collision energies is constructed. Anomalous fractal dimensions and parameters characterizing an associated medium for both classes of events are established. The basic features of the scaling established in minimum bias events are shown to be preserved up to the highest multiplicity densities measured in the experiments UA1, E735, CDF, and STAR. The obtained results are of interest for use of z-scaling as a tool for searching for new physics phenomena of particle production at a high transverse momentum and in the high-multiplicity region at U70, Tevatron, RHIC, and LHC.
