Description

Anisotropic azimuthal correlations are used to probe the properties and the evolution of the system created in heavy-ion collisions. Hydrodynamic model calculations predict that there are effects of $p_{\rm T}$ dependent fluctuations of the flow angle and flow magnitude, which might bias our previous anisotropic flow measurements. In this talk, the two effects will be investigated in both Pb-Pb and p-Pb collisions, using two-particle azimuthal correlation measurements with the ALICE detector. In addition, the factorization of the two-particle Fourier harmonics $V_{n\Delta}$ for different values of $n$ into single-particle azimuthal anisotropies $v_{n}$, will be discussed. Our measurements, together with the comparison to hydrodynamic model calculations will open a new window on the study of the initial state fluctuations and the extraction of shear viscosity of the quark-gluon plasma at the LHC.
