    Light nuclei collectivity from root s(NN)=3 GeV Au+Au collisions at RHIC

  • Original language description

    In high-energy heavy-ion collisions, partonic collectivity is evidenced by the constituent quark number scaling of elliptic flow anisotropy for identified hadrons. A breaking of this scaling and dominance of baryonic interactions is found for identified hadron collective flow measurements in root s(NN) = 3 GeV Au+Au collisions. In this paper, we report measurements of the first- and second-order azimuthal anisotropic parameters, v(1) and v(2), of light nuclei (d, t, He-3, He-4) produced in root s(NN) = 3 GeV Au+Au collisions at the STAR experiment. An atomic mass number scaling is found in the measured v(1) slopes of light nuclei at mid-rapidity. For the measured v(2) magnitude, a strong rapidity dependence is observed. Unlike v(2) at higher collision energies, the v(2) values at mid-rapidity for all light nuclei are negative and no scaling is observed with the atomic mass number. Calculations by the Jet AA Microscopic Transport Model (JAM), with baryonic mean-field plus nucleon coalescence, are in good agreement with our observations, implying baryonic interactions dominate the collective dynamics in 3 GeV Au+Au collisions at RHIC.
