| dc.description | We studied single $W$ boson production in high energy $eγ$ collisions and the sensitivity of various observables to the $WWγ$ gauge boson coupling by evaluating the helicity amplitudes of all Feynman diagrams which contribute to the final state being studied, including the $W$ decay to final state fermions. We examined $W$ production at 500 GeV and 1 TeV $e^+e^-$ colliders, comparing results for photon spectra obtained from a backscattered laser and from beamstrahlung radiation. Here we found that the couplings could best be measured using the backscattered laser photons with $|δκ_γ|\leq 0.07$ and $|λ_γ| \leq 0.05$ at a 500 GeV collider and $|δκ_γ|\leq 0.07$ and $|λ_γ| \leq 0.02$ at a 1 TeV collider, all at 95% C.L.. The measurement of $κ_γ$ is at the threshold of being able to measure loop contributions to the trilinear gauge boson vertex. For completeness we include the limits achievable using single $W$ production at a 200 GeV $e^+e^-$ collider in the Weizacker-Williams approximation. This process can measure $κ_γ$ to $\pm 0.15$ at 95% C.L. which is comparable to the $W$ pair production process. | |
