Phenomenology of single-Wproduction ineγcollisions

We have studied the phenomenology of single-charged-weak-boson production in e{γ} collisions. The cross sections are comparable to the e⁺{e}^{{{-}}}→{W}⁺W^- cross section expected at the LEP II e⁺{e}^{{{-}}}$ collider at CERN once branching fractions for W decay into final-state fermions are taken into account. Using the hadronic decay modes of the W we estimate that ${M}W$ and ${{Γ}}Wcould be measured to similar precision as LEP II experiments using comparable integrated luminosities. However, the process eγ→W{{ν}}ₑ$ is especially sensitive to the anomalous magnetic moment of the W, ${{κ}}_{{γ}}$, and as such offers a good opportunity to test the gauge structure of the standard model at the tree level and at the one-loop level. Our conclusion is that the feasibility of building a high-luminosity e{γ} collider is definitely worth studying.
