摘要
Measurements of anisotropic flow in heavy-ion collisions provide evidence for the creation of strongly interacting matter which appears to behave as an almost ideal fluid. Anisotropic flow signals the presence of multiple interactions and is very sensitive to the initial spatial anisotropy of the overlap region in noncentral heavy-ion collisions. In this paper, we report measurements of elliptic v(2), triangular v(3), quadrangular v(4) and pentagonal v(5) flow. These measurements have been performed with 2- and multi-particle correlation techniques.
