Abstract
We examine the potential of a future 500 GeV linear e{sup +}e{sup -} collider (NLC) to probe the `minimal` set ({kappa}{sub {gamma}}, {lambda}{sub {gamma}}) of anomalous WW{sub {gamma}} and WW{sub {gamma}{gamma}} couplings via the (sub) processes {gamma}{gamma} {yields} W{sup +}W{sup -}, e{sup -}{gamma} {yields} W{sup -}{nu} and e{sup +}e{sup -} {yields} W{sup +}W{sup -}, for comparison. Photon beams both from classical Bremsstrahlung and, notably, from backscattering laser light off e{sup {+-}} beams are considered. The differential cross sections d{sigma}/dcos {theta} of the three reactions are calculated analytically and used as observables in a {chi}{sup 2} analysis under identical assumptions on machine parameters. The constraints emerging from the use of laser photon beams appear very encouraging, are independent of {kappa}{sub Z} and {lambda}{sub Z} and impressively underline the importance of realizing laser photon beams at the NLC.
