Abstract: Results of analysis of experimental data on inclusive cross sections of jets, direct photons, and high-pT hadrons produced in pp= ¯ pp and AA collisions are presented in the framework of zscaling. The data were obtained at ISR, S¯ppS, RHIC, and Tevatron. New properties of zpresentation of the inclusive spectra are discussed. A physical interpretation of the variable z and the scaling function y(z) is given. A microscopic scenario of hadron and nucleus collisions at a constituent level in terms of momentum fractions is developed. The z-scaling re ects the structure of the colliding objects, interaction of their constituents, and particle formation and manifests the general properties of self-similarity, locality, and fractality. The obtained results could be used for searching for new physics phenomena in high energy hadron and nucleus collisions in soft and hard regions at RHIC, Tevatron, and LHC.
