Erratum to: Search for single top-quark production via flavour-changing neutral currents at 8 TeV with the ATLAS detector
One correction is noted for the paper. The branching fraction ($$\mathcal{B}$$($$W →{ℓv}$$) = 0.3246 was not included in the conversion of the observed cross-section limit, σ x $$\mathcal{B}$$( $t →Wb$) x ($$\mathcal{B}$$($$W →{ℓv}$$) < 2.9to the coupling constants $$κ_{ugt}$$ and $$κ_{cgt}$$ and the branching fractions $$\mathcal{B}$$( $t →ug$) and $$\mathcal{B}$$( $t →cg$). The inclusion leads to weaker observed exclusion limits on the coupling constants divided by the scale of new physics of $$k_{ugt}$$/ Λ <10 x 10-3 TeV-1 and $$k_{cgt}$$/Λ <23 x 10-3 TeV-1 and on the branching fractions $$\mathcal{B}$$( $t →ug$) < 1.2 x10-4 and $$\mathcal{B}$$( $t →cg$) < 6.4 x 10-4. The predicted exclusion limits on the coupling constants divided by the scale of new physics are $$k_{ugt}$$/ Λ < 9.5 x 10-3 TeV-1and $$\mathcal{B}$$( $t →cg$)/ Λ < 22 x 10-3 TeV-1 and on the branching fractions $$\mathcal{B}$$( $t →ug$) < 1.1 x 10-4 and $$\mathcal{B}$$( $t →cg$) < 5.7 x 10-4. Updated distributions of the observed upper limits on the coupling constants for combinations of cgt and ugt channels are shown in Figure 10a and on the branching fractions in Figure 10b.
