    <description descriptionType="Abstract">&lt;p&gt;Parton energy loss in the quark–gluon plasma (QGP) is studied with a measurement of photon-tagged jet production in 1.7 nb$^{−1}$ of Pb+Pb data and 260 pb$^{−1}$ of pp data, both at $\sqrt{{s}_{\mathrm{NN}}}=5.02$ TeV, with the ATLAS detector. The process pp →γ+jet+X and its analogue in Pb+Pb collisions is measured in events containing an isolated photon with transverse momentum (${p}_{T}$) above 50 GeV and reported as a function of jet ${p}_{T}$. This selection results in a sample of jets with a steeply falling ${p}_{T}$ distribution that are mostly initiated by the showering of quarks. The pp and Pb+Pb measurements are used to report the nuclear modification factor, ${R}_{\mathrm{AA}}$, and the fractional energy loss, ${S}_{\mathrm{loss}}$, for photon-tagged jets. In addition, the results are compared with the analogous ones for inclusive jets, which have a significantly smaller quark-initiated fraction. The ${R}_{\mathrm{AA}}$ and ${S}_{\mathrm{loss}}$ values are found to be significantly different between those for photon-tagged jets and inclusive jets, demonstrating that energy loss in the QGP is sensitive to the colour-charge of the initiating parton. The results are also compared with a variety of theoretical models of colour-charge-dependent energy loss.&lt;/p&gt;</description>
