High energy single top photoproduction at the LHC

Understand

High-energy photon-proton interactions at the LHC offer interesting possibilities for the study of top properties.

• Using a fast simulation of a LHC-like detector, first results on the measurement of the |V_{tb}| matrix element using Wt photoproduction are presented.
• Anomalous photoproduction of single top due to Flavour-Changing Neutral Currents permits to improve the current limits on the coupling parameters, k_{tu\gamma} and k_{tc\gamma} after only 1 fb^{-1}.
