We have examined the constraints on the anomalous tq gamma (q = u, c) couplings through the process pp -> p gamma p -> pWbX at the LHC by considering four forward detector acceptances: 0.0015 < xi < 0.5, 0.0015 < xi < 0.15, 0.015 < xi < 0.15, and 0.1 < xi < 0.5, where xi = E-gamma/E with E-gamma and E the energies of the photon and of the incoming proton, respectively. The sensitivity bounds on the anomalous couplings have been obtained at the 95% confidence level in a model independent effective Lagrangian approach. We have found that the bounds on these couplings can be highly improved compared to current experimental bounds.
