A search for single top-quark production via flavour-changing neutral current processes from gluon plus up- or charm-quark initial states in proton\u2013proton collisions at the LHC is presented. Data collected with the ATLAS detector in 2012 at a centre-of-mass energy of 8\ua0TeV and corresponding to an integrated luminosity of 20.3\ua0fb (Formula presented.) are used. Candidate events for a top quark decaying into a lepton, a neutrino and a jet are selected and classified into signal- and background-like candidates using a neural network. No signal is observed and an upper limit on the production cross-section multiplied by the (Formula presented.) branching fraction is set. The observed 95\ua0% CL limit is (Formula presented.) and the ex...
