Spectra of negative particles in Au plus Au collisions from BES-I at RHIC and z-scaling

Original language description

Negative particle yields in Au + Au collisions obtained by the STAR Collaboration from BES-I at RHIC are analyzed in the framework of 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 at vertical bar eta vertical bar < 0.5. The scaling behavior of the spectra as a function of the collision energy and centrality in z-presentation is verified. The constituent energy loss in dependence on the energy and centrality of collision and transverse momentum of inclusive particle is estimated. New indication on self-similarity of fractal structure of nuclei and fragmentation process is found. A discontinuity of the model parameters - fractal and fragmentation dimensions and specific heat - is considered from the point of view of a phase transition in nuclear matter.
