High-energy photon-proton interactions at the LHC offer interesting possibilities for the study of the electroweak sector up to TeV scale and searches for processes beyond the Standard Model. An analysis of the W associated single top photoproduction has been performed using the adapted MadGraph/MadEvent [1]and CalcHEP [2] programs interfaced to the Pythia [3] generator and a fast detector simulation program. Event selection and suppression of main backgrounds have been studied. A comparable sensitivity to vertical bar V(tb)vertical bar to those obtained using the standard single top production in pp collisions has been achieved already for 10 fb(-1) of integrated luminosity. Photoproduction at the LHC provides also an attractive framework for observation of the anomalous production of single top due to Flavour-Changing Neutral Currents. The sensitivity to anomalous coupling parameters, k(tu gamma)., and k(tc gamma) is presented and indicates that stronger limits can be placed on anomalous couplings after 1 fb(-1).
