  New analysis of experimental data on hadron (pi, K, barp) production in p-p
and p-D collisions at high-pT in z-presentation is performed. Data on inclusive
cross sections of cumulative particles produced in backward hemisphere in p-A
collisions are analyzed as well. The scaling function for nuclear targets (Li,
Be, C, Al, Cu and Ta) are constructed and compared with high-pT data
z-presentation. The hypothesis on z-scaling violation as a signature of new
physics phenomena is discussed.
