  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.
