Search for single top-quark production via flavour-changing neutral currents at 8 TeV with the ATLAS detector
Original language description
A search for single top-quark production via flavour-changing neutral current processes from gluon plus up- or charm-quark initial states in proton–proton collisions at the LHC is presented. Data collected with the ATLAS detector in 2012 at a centre-of-mass energy of 8 TeV and corresponding to an integrated luminosity of 20.3 fb1 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 tWb branching fraction is set. The observed 95 % CL limit is σqgtB(tWb)<3.4pb and the expected 95 % CL limit is σqgtB(tWb)<2.9pb . The observed limit can be interpreted as upper limits on the coupling constants of the flavour-changing neutral current interactions divided by the scale of new physics κugt/Λ<5.8103TeV1 and κcgt/Λ<13103TeV and on the branching fractions B(tug)<4.0105 and B(tcg)<20105 .n
