Abstract

We investigate the constraints on the anomalous WWH couplings through the process e(-)gamma -> nu eW-H. Considering incoming beam polarizations and the longitudinal and transverse polarization states of the final W boson, we find 95% confidence level limits on the anomalous coupling parameters with an integrated luminosity of 500 fb(-1) and root s = 0.5 and 1 TeV energy. We show that initial beam and final state polarizations highly improve the sensitivity limits of the anomalous coupling parameters b(W) and beta(W).
