### Description

It has been shown that high energy partons lose energy when traversing the hot, dense medium produced in heavy-ion collisions. However, the mechanism of the energy loss, including its dependence on the path-length of the shower in the medium, is not fully understood. This poster presents a measurement of single jet yields as a function of the azimuthal angle with respect to the event plane in Pb+Pb collisions at $\sqrt{s_{NN}} = 5.02$~TeV. Because jets at different angles with respect to the event plane traverse, on average, different path lengths of the medium, this measurement gives insight into the path-length dependence of parton energy loss. The azimuthal angle dependence of the yields is characterized by the parameter $v_{n}^{jet}$, which quantifies the magnitude of the modulation of the azimuthal angle distribution with respect to the $n^{th}$ order event plane. While ATLAS has previously reported the $v_{2}^{jet}$ in Pb+Pb at $\sqrt{s_{NN}} = 2.76$~TeV, this is the first ATLAS measurement of higher order $v_{n}^{jet}$.
