Polarized single top quark production in eγ collision and anomalous Wtb couplings

We investigate the potential of eγ collisions to probe anomalous Wtb couplings via the polarized single top quark production process e+γ→tb̄νē. We find 95% confidence level limits on the anomalous coupling parameters F2L and F2R with an integrated luminosity of 500 fb-1 and \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$\sqrt{s}=0.5$\end{document}, 1 and 1.5 TeV energies. The effects of top quark spin polarization on the anomalous Wtb couplings are discussed. It is shown that polarization leads to a considerable improvement in the sensitivity limits.
