Azimuthal anisotropies of reconstructed jets [vnjet\phantom\rule4pt0ex(n=2,3)] have been investigated in Pb + Pb collisions at the center of mass energy √sNN=2.76 TeV within a framework of a multiphase transport (AMPT) model. The v2jet is in good agreement with the recent ATLAS data. However, the v3jet shows a smaller magnitude than v2jet, 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 vnjet/\ensuremathεn increases from peripheral to noncentral collisions, and vnjet increases with the initial spatial asymmetry (\ensuremathεn) for a given centrality bin. These behaviors indicate that the vnjet 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.
