Abstract We present the first fully-corrected semi-inclusive distribution of charged jets recoiling from a trigger hadron in 0-10% Pb--Pb collisions at sNN = 5.02 TeV as a function of the azimuthal angle between the trigger hadron and jet, Δφ. This technique provides a precise data-driven subtraction of the large uncorrelated background contaminating the measurement, and enables the exploration of jet acoplanarity. Results for R=0.2 recoil jets in the region 30<pT,jetch<40GeV/c are shown, where a suppression and narrowing of the Δφ distribution is observed in 0-10% Pb--Pb collisions with respect to a PYTHIA pp reference.
