New experimental data on inclusive spectra of identified particles produced
in pp collisions at the RHIC are used to test z-scaling. Energy and
multiplicity independence of the scaling function is established. The RHIC data
confirm z-scaling observed at U70, ISR, SpS and Tevatron energies. The obtained
results are of interest to search for new physics phenomena of particle
production in high transverse momentum and high multiplicity region at RHIC,
Tevatron and LHC.Comment: 6 pages, LaTeX, 12 figures, Presented at the XXXV International
