Net baryon content of the partonic distribution function of gold-nucleus at the factorization scales ($Q_0^2$) of $0.50{\mathrm{G}\mathrm{e}\mathrm{V}}^2$ (solid curve), $1.00{\mathrm{G}\mathrm{e}\mathrm{V}}^2$ (dashed curve), and $2.00{\mathrm{G}\mathrm{e}\mathrm{V}}^2$ (dot-dashed curve), for the GRV-HO [10] parametrization. Parton shadowing is not included.Reuse & Permissions

Figure 2

Net baryon rapidity distributions for $\mathrm{A}\mathrm{u}+\mathrm{A}\mathrm{u}$ reactions at ${\sqrt{s}}_{NN}=130\mathrm{G}\mathrm{e}\mathrm{V}$ (top) and ${\sqrt{s}}_{NN}=200\mathrm{G}\mathrm{e}\mathrm{V}$ bottom. Crosses denote a calculation in which the PCM has been restricted to primary parton scatterings, diamonds include parton rescattering, and squares include rescattering and parton fragmentation. The solid lines show the net baryon content of the partonic distribution functions for gold nuclei, scaled by an average liberation factor of 0.4 . The band at $y_{CM}$ shows the range of experimental estimates for the net-baryon density by STAR, BRAHMS, and PHENIX.Reuse & Permissions
