Anomalous Higgs couplings in egamma collision with initial beam and final state polarizations

Abstract

We investigate the constraints on the anomalous WWH couplings through the process $e^{-}\gamma \to {\nu }_e{W}^{-}H$. 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 $f{b}^{-1}$ and $\sqrt{s}$= 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 ${\beta }_W$.
