Validation of z-scaling for negative particle production in Au plus Au collisions from BES-I at STAR

Popis výsledku v původním jazyce

We present results of analysis of negative particle spectra in Au + Au collisions obtained by the STAR Collaboration in the first phase of the Beam Energy Scan program at RHIC using the z-scaling approach. 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 in the pseudo-rapidity range vertical bar eta vertical bar < 0.5. A scaling behavior of the spectra as a function of the collision energy and centrality in z-presentation is observed. The concept of the z-scaling based on fundamental principles of self-similarity, locality, and fractality of hadron interactions at high energies is considered. The energy loss as a function of the energy and centrality of the collision and the transverse momentum of inclusive particle is estimated. New indication on self-similarity of fractal structure of nuclei and fragmentation processes with negative particles produced in Au + Au collisions at RHIC is found.
