Isolated Photon–Jet Correlations in Pb–Pb Collisions at \(\sqrt {s_{NN}} = 5.02\) TeV in ALICE

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 \(Q^2\) of the initial hard scattering. We present the isolated photon–jet correlations measured in Pb–Pb collisions at \(\sqrt {s_{NN}} = 5.02\) 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-\(k_\mathrm {T}\) algorithm. The correlations probe the lowest jet \(p_\mathrm {T}\) range ever measured at LHC energies, and larger modifications due to the QGP are expected in the lower \(p_\mathrm {T}\) regime.
