The spectra were measured over a wide range of collision energy root S-NN = 7.7 - 200 GeV and transverse momentum of produced particles for different centralities at eta < 0.5. The concept of thez-scaling based on self-similarity, locality, and fractality of hadron interactions at a constituent level is verified. The constituent energy loss as a function of energy and centrality of collision and transverse momentum of inclusive particle was estimated.
