摘要：

By means of the AKK08 fragmentation function, the net-proton transverse momentum (p(T)) spectra in A + A collisions are studied with two phenomenological models based on the Color Glass Condensate formalism. After a chi(2) analysis of the experimental data from BRAHMS, the normalization constant C is extracted at RHIC energies of root s(NN) = 62.4 and 200 GeV, and the theoretical results of the net-proton p(T) spectra at selected rapidities are also given. It is shown that the theoretical results are in good agreement with the experimental data. Finally, assuming the constant C should have an exponent dependence of root s(NN), we also predict the theoretical results of net-proton PT spectra at LHC energies of root s(NN) = 2.76, 3.94, and 5.52 TeV.
