Title: Investigations of the linear and non-linear flow harmonics using the a multi-phase transport model

Journal Article · · Journal of Physics. G, Nuclear and Particle Physics

The multi-phase transport model (AMPT) is used to study the effects of the parton-scattering cross-sections (σpp) and hadronic re-scattering on the linear contributions to the flow harmonic v4, the non-linear response coefficients, and the correlations between different order flow symmetry planes in Au + Au collisions at 200 GeV. The model results, which agree with current experimental measurements, indicate that the higher-order flow harmonics are sensitive to the σpp variations. However, the non-linear response coefficients and the correlations between different order flow symmetry planes are σpp independent. Furthermore, these results suggest that further detailed experimental measurements which span a broad range of collision systems and beam energies could serve as an additional constraint for the theoretical models' calculations.
