Considering the experimental constraints given by the CMS collaboration at $$\sqrt{s} = 8$$ s = 8 TeV on the strength of top quark flavour-changing neutral-current couplings $$tq\gamma $$ t q γ and tqg, we investigate the production of top quark in association with a photon and carry out a full simulation for the signals $$\ell \nu b\gamma $$ ℓ ν b γ and $$jjb\gamma $$ j j b γ at 14 TeV LHC. In our numerical analysis, the contributions of single top production with a photon radiation off the top decay products are also included. The discovery potential for anomalous couplings $$tq\gamma $$ t q γ and tqg with an integrated luminosity of 100 fb $$^{-1}$$ - 1 is examined in detail.
