Isolated photon-jet correlations in 5.02 TeV Pb-Pb collisions with ALICE

Jets correlated with isolated photons are a promising channel to study jet quenching in heavy-ion collisions, as photons do not participate in the strong interaction and therefore constrain the $Q^2$ of the initial hard scattering. We present isolated photon-jet correlations measured in Pb–Pb collis...

description Jets correlated with isolated photons are a promising channel to study jet quenching in heavy-ion collisions, as photons do not participate in the strong interaction and therefore constrain the $Q^2$ of the initial hard scattering. We present isolated photon-jet correlations measured in Pb–Pb collisions at $\sqrt{^snn}$ = = 5.02 TeV by the ALICE collaboration. We study correlations of isolated photons with 28 < $pT$ < 40 GeV/c with charged-particle jets with $pT$ > 10 GeV/c reconstructed with the anti-$kT$ algorithm and report the azimuthal correlation and $pT$ asymmetry. The correlations probe the lowest jet $pT$ range ever measured at LHC energies, and larger modifications due to the $QGP$ are expected in the lower $pT$ regime. We see no trend in the away-side yield with centrality, but do see a change in the distribution of the $pT$ asymmetry consistent with increasing jet energy loss in more central collisions.
