Space-momentum correlations in 8 AGeV Au+Au collisions

  • Within the RQMD model, space-momentum correlations, i.e. the correlations between final momentum anisotropy and initial eccentricity, are studied for 8 AGeV Au+Au events classified according to the multi-particle azimuthal correlations. The results show that the final elliptic flow fluctuations depend on the initial collision geometry. There are clear space-momentum correlations for
    nucleons during the whole dynamical evolution of the collisions.

Space-momentum correlations in 8 AGeV Au+Au collisions

    Corresponding author: HUO Lei,

Abstract: 

Within the RQMD model, space-momentum correlations, i.e. the correlations between final momentum anisotropy and initial eccentricity, are studied for 8 AGeV Au+Au events classified according to the multi-particle azimuthal correlations. The results show that the final elliptic flow fluctuations depend on the initial collision geometry. There are clear space-momentum correlations for
nucleons during the whole dynamical evolution of the collisions.
