New results of analysis of K 0 S −meson spectra measured over a wide range of energy √ s N N = 7.7 − 200 GeV and centrality in Au + Au collisions by the STAR Collaboration at RHIC using the z-scaling approach are presented. Indication on self-similarity of fractal structure of nuclei and fragmentation processes with K 0 S probe is demonstrated. The energy loss as a function of the collision energy, centrality and transverse momentum of the inclusive strange meson is estimated.
