Abstract (data abstract)
Search for flavour-changing neutral-current couplings between the top-quark and the photon with the ATLAS detector at $\sqrt{s} = 13$ TeV The analysis uses data collected in $pp$ collisions at $\sqrt{s} = 13$~TeV during the LHC Run 2 corresponding to an integrated luminosity of 139~fb$^{-1}$. Both FCNC top-quark production and decay are considered. The final state consists of a charged lepton, missing transverse momentum, a $b$-tagged jet, one high momentum photon and possibly additional jets. A multiclass deep neural network is used to classify events as either one of the two signal categories, FCNC production or decay, or as background. # hepdata_doi: 10.17182/hepdata.105039.v1
