### Description

Heavy nuclei colliding at ultra-relativistic energies at the Large Hadron Collider (LHC) produce a hot and dense state of matter filled with deconfined quarks and gluons. Particles produced by hard-scatterings interact with the hot and dense medium as they propagate through it, in a process known as jet quenching.

The medium-induced modification of the jet-like particle yield can be quantified in azimuthal di-hadron correlations with the observable $I_{\mathrm{AA}}$, which is the ratio of the jet peak yield in Pb--Pb collisions to pp collisions. The path-length dependence of the jet modification is investigated by studying $I_{\mathrm{AA}}$ as a function of the relative angle between the trigger particle and the event plane. Results are shown as a function of centrality and transverse momentum of the associated particles for Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 2.76 TeV, and compared to AMPT model calculations.
