Jet quenching and acoplanarity via hadron-jet measurements in pp and Pb–Pb collisions at 5.02 TeV with ALICE

Measurements of the semi-inclusive distribution of charged jets recoiling from a trigger hadron in pp and Pb–Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02\text{TeV}$ are presented. This technique provides precise, data-driven subtraction of the large uncorrelated background in jet measurements. It uniquely enables the exploration of medium-induced modification of jet production and acoplanarity over wide phase space, including low transverse momentum (p_T) and large resolution parameter (R) jets. This proceeding reports the measurements of medium-induced jet energy redistribution through the comparison of trigger-normalized recoil jet yields in pp and Pb–Pb collisions, and for jets with different R.
