Abstract
The anisotropic flow of charged hadrons in asymmetric $\text{Cu}+\text{Au}$ collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. Compared with previous results for symmetric $\text{Au}+\text{Au}$ collisions, charged hadrons produced around midrapidity in asymmetric collisions are found to have a stronger directed flow ${v}_{1}$ and their elliptic flow ${v}_{2}$ is also more sensitive to the parton scattering cross section. Although higher order flows ${v}_{3}$ and ${v}_{4}$ are small at all rapidities, both ${v}_{1}$ and ${v}_{2}$ in these collisions are appreciable and show an asymmetry in forward and backward rapidities.
