Z-scaling from tens of GeV to TeV

Abstract

The concept of z-scaling reflecting the general features of internal particle substructure, constituent interaction and mechanism of particle formation at high-pT is reviewed. Experimental data on inclusive cross sections obtained at U70, ISR, SpS, RHIC and Tevatron are used in the analysis. The properties of data z-presentation such as the energy independence, power law and A-dependence are discussed. The properties of z-scaling are argued to be connected with the fundamental symmetries such as self-similarity, locality and fractality. The use of z-scaling to search for new physics phenomena in hadron-hadron and hadron-nucleus collisions is suggested. RHIC data used in our new analysis confirm z-scaling in pp collisions. High-pT particle spectra at LHC energies are predicted. Violation of z-scaling characterized by the change of anomalous fractal dimension is considered as a new and complementary signature of new physics phenomena.
