Description
Elliptic ($v_2$) and triangular ($v_3$) anisotropic flow coefficients for inclusive and identified charged hadrons ($\pi^{\pm}$,K$^{\pm}$,(anti)protons) at midrapidity in Au+Au collisions measured by the STAR experiment in the Beam Energy Scan at the Relativistic Heavy Ion Collider at $\sqrt{s_{NN}}$ = 11.5–62.4 GeV and 200 GeV are presented as a function of centrality and particle transverse momenta. The triangular flow signal ($v_3$) exhibits similar trends to those observed previously for $v_2$: mass ordering at low $p_T$ ($p_T<2$ GeV/c), meson/baryon splitting at intermediate $p_T$ ($2< p_T < 3.5$ GeV/c), difference in flow signal of protons and antiprotons and similar excitation function for $p_T$-integrated values of charged hadrons. New measurements of $v_3$ could serve as important constraints to test different models and to aid new information of transport properties of the matter created in heavy-ion collisions at RHIC energies.
