Abstract
New scaling, z scaling, in the inclusive particle production in collisions is studied. The concept of z scaling is based on fundamental principles such as self-similarity, locality, scale relativity, and fractality reflecting the general features of particle interactions. The scaling function is expressed via the invariant cross section and the average multiplicity density of particles produced at pseudorapidity in the corresponding nucleon-nucleon interaction. The dependence of on scaling variable , the center-of-mass energy and the atomic number A is investigated. It is shown that the available experimental data on cross sections in collisions confirm the scaling properties of the function The obtained results can be of interest for future experiments at BNL relativistic heavy-ion collider and CERN large hadron collider in searching for new physical phenomena in and collisions.
