Self-Similarity of Negative Particle Production in Au + Au Collisions at STAR

Results of a new analysis of negative particle yields in Au + Au collisions obtained by the STAR Collaboration in the first phase of the RHIC Beam Energy Scan (BES) program in the framework of -scaling approach are presented. The spectra were measured over a wide range of collision energy GeV and tr...

Description
Summary:Results of a new analysis of negative particle yields in Au + Au collisions obtained by the STAR Collaboration in the first phase of the RHIC Beam Energy Scan (BES) program in the framework of -scaling approach are presented. The spectra were measured over a wide range of collision energy GeV and transverse momentum of produced particles for different centralities at The concept of the -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.
