Description
Results of a new analysis of negative charged particle yields in $Au+Au$ collisionsas a function of transverse momentum obtained by the STAR Collaboration for the first phase of the RHIC Beam Energy Scan Program in the framework of the $z$-scaling approach are presented.The spectra were measured over a wide range of collision energy $sqrt {s_{NN}}~=~7.7-200$~GeV and transverse momentum of produced particles in different centralities at $|eta|
