Abstract
Anisotropic azimuthal correlations are used to probe the properties and the evolution of the system created in heavy-ion collisions. Two-particle azimuthal correlations were used in the searches of $p_{\rm T}$ dependent fluctuations of flow angle and magnitude, measured with the ALICE detector. The comparison of hydrodynamic calculations with measurements will also be presented in this proceedings.

The primary goal of ultra relativistic heavy-ion collisions is to understand the properties of the quark-gluon plasma (QGP), a new state of matter whose existence under extreme conditions is predicted by quantum chromodynamics
Vn{2}/vn[2] and rn were proposed in hydrodynamic calculations [3, 4]. They are used to check whether the factorization of two-particle correlations into the product of single particle anisotropy harmonics is valid, which probes the pT dependent flow angle and magnitude fluctuations

Summary
The primary goal of ultra relativistic heavy-ion collisions is to understand the properties of the quark-gluon plasma (QGP), a new state of matter whose existence under extreme conditions is predicted by quantum chromodynamics. An important experimental observable toward this goal is the study of anisotropic flow using a Fourier expansion of the azimuthal anisotropy [1], d3N E d3p. Recent hydrodynamic simulations predict the pT dependent fluctuations of flow angle and magnitude. Vn{2}/vn[2] and rn were proposed in hydrodynamic calculations [3, 4]. They are used to check whether the factorization of two-particle correlations into the product of single particle anisotropy harmonics is valid, which probes the pT dependent flow angle and magnitude fluctuations.
