AbstractAzimuthal anisotropies of reconstructed jets [v(n)(jet) (n = 2,3)] have been investigated in Pb + Pb collisions at the center of mass energy root S-NN = 2.76 TeV within a framework of a multiphase transport (AMPT) model. The v(2)(jet) is in good agreement with the recent ATLAS data. However, the v(3)(jet) shows a smaller magnitude than v(2)(jet), and approaches zero at a larger transverse momentum. It is attributed to the path-length dependence in which the jet energy loss fraction depends on the azimuthal angles with respect to different orders of event planes. The ratio v(n)(jet)/epsilon(n) increases from peripheral to noncentral collisions, and v(n)(jet) increases with the initial spatial asymmetry (epsilon(n)) for a given centrality bin. These behaviors indicate that the v(n)(jet) is produced by the strong interactions between jet and the partonic medium with different initial geometry shapes. Therefore, azimuthal anisotropies of reconstructed jet are proposed as a good probe to study the initial spatial fluctuations, which are expected to provide constraints on the path-length dependence of jet quenching models.
