Description
z-Scaling of inclusive spectra as a manifestation of self-similarity and fractality of hadron interactions is illustrated. The scaling for negative particle production in Au+Au collisions from BES-I at RHIC is demonstrated. The scaling variable z depends on momentum fractions of colliding objects carried by the interacting constituents and momentum fractions of the scattered and recoil constituents carried by the inclusive particle and its counterpart. Structures of the colliding objects and fragmentation processes are expressed by fractal dimensions. Produced medium is described by a specific heat. The scaling function reveals energy, angular, multiplicity, and flavor independence. It has a power behavior at high z (high pT). Based on entropy principle and z-scaling, energy loss as a function of the collision energy, centrality and pT of inclusive particle is estimated. New conservation law including fractal dimensions is found. Quantization of fractal dimensions is discussed.
