Self-Similarity of $\boldsymbol{K}_{\boldsymbol{S}}^{\mathbf{0}}$-Meson Production in Au + Au Collisions at RHIC

Abstract

New results of analysis of $K^{0}_{S}$-meson spectra in $Au+Au$ collisions obtained by the STAR Collaboration at RHIC using the $z$-scaling approach are presented. The spectra were measured over a wide range of collision energy $\sqrt{s_{NN}}=7.7-200$ GeV, transverse momentum of produced particles and different centralities in the rapidity range $|y|<0.5$. The self-similarity of the $K_{S}^{0}$ spectra in $z$-presentation is demonstrated. The energy loss as a function of the collision energy and the transverse momentum of $K_{S}^{0}$ meson for 0–5% centrality is estimated.
