摘要：

Considering the experimental constraints given by the CMS collaboration at root s = 8 TeV on the strength of top quark flavour-changing neutral-current couplings tq. and tqg, we investigate the production of top quark in association with a photon and carry out a full simulation for the signals l nu b gamma. and jjb gamma. 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. and tqg with an integrated luminosity of 100 fb(-1) is examined in detail.
