Observing anomalous di-boson couplings in the WWgamma vertex at CMS

This note presents a study of the CP conserving anomalous couplings, Delta kappa and lambda, of the WWgamma vertex. An independent NLL Monte Carlo event generator has been combined with the CMSJET detector simulation to provide a realistic simulation of the process at CMS. The methods to determine the presence of anomalous couplings have been evaluated. We show that the photon transverse momentum spectrum is the most sensitive to Standard Model deviations and will provide greatly improved sensitivites of Delta kappa and lambda at the LHC energies.
