• Collective flows in heavy-ion collisions from AGS [(2–11)A GeV] to SPS [(40, 158)A GeV] energies areinvestigated in a nonequilibrium transport model with the nuclear mean field (MF). Sideward 〈Px〉, directedv1, and elliptic flows v2 are systematically studied with different assumptions for the nuclear equation of state(EOS). We find that the momentum dependence on the nuclear MF is important for the understanding of theproton collective flows at AGS and SPS energies. Calculated results with momentum-dependent MF qualitativelyreproduce the experimental data of proton sideward, directed, and elliptic flows in a incident energy range of(2–158)A GeV.
