Abstract

In this work, we study the charged hadron anisotropic flow coefficients v_n (up to n = 12) using high-statistics event-by-event simulations of Pb+Pb collisions at √(s_NN) = 5.02 and 5.36~TeV, employing the IP-Glasma + MUSIC + UrQMD hybrid approach. The power spectra of anisotropic flow coefficients (v_n\2\ vs. n) are compared with the ALICE measurements from central to 50% centrality. To understand the various sources contributing to the high-order v_n coefficients, we analyze the nonlinear mode coefficients for high-order anisotropic flow coefficients using different approximations and make comparisons with available measurements.
