Abstract :
Single W-boson production in e−λ collisions with polarized beams is investigated. Helicity amplitudes for general couplings and masses are derived and their properties are discussed. The results are applied to study the Standard Model. Updated estimates of the measurement precision of the photon anomalous coupling parameters κγ, λγ at the NLC with √See = 500 GeV are obtained. Comparison with the earlier works without polarization and with the recent analysis of polarized e−e+ collisions is carried out.
