Z-Scaling and Inclusive Particle Production in p-p Collisions at High-pT

The properties of particle production in pp collisions are basis for analysis of pA and AA interactions and verification of theory. We analyzed inclusive particle production using z -scaling established in proton-proton and proton-antiproton collisions at the U70, ISR, Tevatron and RHIC. This scaling reflects symmetry of hadron structure, interaction and particle formation. It is shown that new data on charged hadron and π 0 -meson spectra obtained in pp collisions at the Relativistic Heavy Ion Collider confirm the z -scaling.
