Proton, deuteron and triton flow measurements in Au plus Au collisions at root √sNN=2.4 GeV
Original language description
High-precision measurements of flow coefficients v(n) (n = 1 - 4) for protons, deuterons and tritons relative to the first-order spectator plane have been performed in Au+Au collisions at root s(NN) = 2.4 GeV with the High-Acceptance Di-Electron Spectrometer (HADES) at the SIS18/GSI. Flow coefficients are studied as a function of transverse momentum p(t) and rapidity y(cm) over a large region of phase-space and for several classes of collision centrality. A clear mass hierarchy, as expected by relativistic hydrodynamics, is found for the slope of v(1), d(v1)/dy'vertical bar y'=0 where y' is the scaled rapidity, and for v(2) at mid-rapidity. Scaling with the number of nucleons is observed for the p(t) dependence of v(2) and v(4) at mid-rapidity, which is indicative for nuclear coalescence as the main process responsible for light nuclei formation. v(2) is found to scale with the initial eccentricity , while v(4) scales with (2) and (.) The multi-differential high-precision data on v(1), v(2), v(3), and v(4) provides important constraints on the equation-of-state of compressed baryonic matter.
