摘要：
Measurements of the semi-inclusive distribution of charged jets recoiling from a trigger hadron in pp and Pb-Pb collisions at root s(NN) = 5.02 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.
