Proton, deuteron and triton flow measurements in Au+Au collisions at √(s_NN) = 2.4 GeV

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 √(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 is found for the slope of v_1, d v_1/d y^'|_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 ⟨ϵ_2⟩, while v_4 scales with ⟨ϵ_2⟩^2 and ⟨ϵ_4⟩. 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.
