Measurement of anisotropic flow for BES-II energies at RHIC from STAR

Anisotropic flow reflects how the medium produced in heavy-ion collisions expands and responds to the initial geometry of the collision. The anisotropic flow coefficients, such as v1 (directed flow), v2 (elliptic flow), and v3 (triangular flow), describe different aspects of this collective motion and are sensitive to the equation of state (EoS) of the created matter. In these proceedings, we report measurements of the flow coefficients using high-statistics data from the RHIC Beam Energy Scan (BES-II), collected with the upgraded STAR detector acceptance, for a broad range of hadron species. The experimental results are compared with theoretical model calculations to gain insights into the underlying physics in the high baryon density region of the QCD phase diagram.
