The process $pp \\to \\gamma$+jet+$X$ and its analogue in Pb+Pb collisions is measured in events containing an isolated photon with transverse momentum ($p_\\mathrm{T}$) above $50$ GeV and reported as a function of jet $p_\\mathrm{T}$. This selection results in a sample of jets with a steeply falling $p_\\mathrm{T}$ 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.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.139723.v1/t1","@type":"Dataset","description":"The differential cross-section of photon-tagged jets as a function of jet $p_{\\mathrm{T}}$ in pp collisions.","name":"Figure 3"},{"@id":"https://doi.org/10.17182/hepdata.139723.v1/t2","@type":"Dataset","description":"The yields of photon-tagged jets as a function of jet $p_{\\mathrm{T}}$ in Pb+Pb collisions for different centrality intervals.","name":"Figure 4"},{"@id":"https://doi.org/10.17182/hepdata.139723.v1/t3","@type":"Dataset","description":"The nuclear modification factor of photon-tagged jets as a function of jet $p_{\\mathrm{T}}$ for different centrality intervals.","name":"Figure 5"},{"@id":"https://doi.org/10.17182/hepdata.139723.v1/t4","@type":"Dataset","description":"The $\\Delta p_{\\mathrm{T}}$ of photon-tagged jets as a function of jet $p_{\\mathrm{T}}$.","name":"Figure 7"},{"@id":"https://doi.org/10.17182/hepdata.139723.v1/t5","@type":"Dataset","description":"The double $R_{\\mathrm{AA}}$ ratio of $R_{\\mathrm{AA}}^{\\gamma\\text{-jet}}/R_{\\mathrm{AA}}^{\\text{inclusive jet}}$ as a function of jet $p_{\\mathrm{T}}$.","name":"Figure 9"},{"@id":"https://doi.org/10.17182/hepdata.139723.v1/t6","@type":"Dataset","description":"The differential cross-section of photon-tagged jets as a function of jet $p_{\\mathrm{T}}$ in pp collisions.","name":"Auxiliary Figure 2"},{"@id":"https://doi.org/10.17182/hepdata.139723.v1/t7","@type":"Dataset","description":"The yields of photon-tagged jets as a function of jet $p_{\\mathrm{T}}$ in Pb+Pb collisions for different centrality intervals.","name":"Auxiliary Figure 3"},{"@id":"https://doi.org/10.17182/hepdata.139723.v1/t8","@type":"Dataset","description":"The nuclear modification factor of photon-tagged jets as a function of jet $p_{\\mathrm{T}}$ for different centrality intervals.","name":"Auxiliary Figure 4"},{"@id":"https://doi.org/10.17182/hepdata.139723.v1/t9","@type":"Dataset","description":"The $\\Delta p_{\\mathrm{T}}$ of photon-tagged jets as a function of jet $p_{\\mathrm{T}}$.","name":"Auxiliary Figure 6"},{"@id":"https://doi.org/10.17182/hepdata.139723.v1/t10","@type":"Dataset","description":"The $R_{\\mathrm{CP}}$ of photon-tagged jets as a function of jet $p_{\\mathrm{T}}$.","name":"Auxiliary Figure 7"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2648097?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/139723"}],"inLanguage":"en","name":"Comparison of inclusive and photon-tagged jet suppression in 5.02 TeV Pb+Pb collisions with ATLAS","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2648097?version=1","version":1}
