Z-scaling at RHIC

Abstract

The concept of z-scaling reflecting the general regularities of high-pT particle production is reviewed. Properties of data z-presentation are discussed. New data on high-pT particle spectra obtained at the RHIC are analyzed in the framework of z-presentation. It was shown that these experimental data confirm z-scaling. Predictions of strange particle spectra are considered to be useful for understanding of strangeness origin in mesons and baryons and search for new physics phenomena at the RHIC.
