Anomalous WWH couplings in gamma gamma collision with initial beams and final state polarizations

Abstract

The constraints on anomalous Higgs boson couplings are investigated through the process $\gamma \gamma \to W^{+}{W}^{-}H$. Considering the longitudinal and transverse polarization states of the final $W^{+}$ and $W^{-}$ bosons and incoming beam polarizations, we find 95% confidence level limits on the anomalous coupling parameters $\Delta a_W$, $b_W$ and ${\beta }_W$ with an integrated luminosity of 500 $f{b}^{-1}$ and $\sqrt{s}$=0.5, 1 TeV energies. We show that initial beam and final state polarizations lead to a significant improvement on the sensitivity limits of the anomalous coupling parameters $b_W$ and ${\beta }_W$.
