Abstract

Jets correlated with isolated photons are a promising channel to study jet quenching in heavy-ion collisions, as photons do not interact strongly and therefore constrain the Q² of the initial hard scattering. We present the isolated photon-jet correlations measured in Pb--Pb collisions at √s_NN = 5.02 TeV by the ALICE collaboration. We study correlations of isolated photons above 20 GeV/c with charged-particle jets above 10 GeV/c, reconstructed with the anti-k_T algorithm. The correlations probe the lowest jet p_T range ever measured at LHC energies, and larger modifications due to the QGP are expected in the lower p_T regime.
