Polarized single top quark production in e gamma collision and anomalous W tb couplings

We investigate the potential of e gamma collisions to probe anomalous Wtb couplings via the polarized single top quark production process e(+)gamma -> t (b) over bar(upsilon) over bar (e). We find 95% confidence level limits on the anomalous coupling parameters F-2L and F-2R with an integrated luminosity of 500 fb(-1) and root s = 0.5, 1 and 1.5 TeV energies. The effects of top quark spin polarization on the anomalous W tb couplings are discussed. It is shown that polarization leads to a considerable improvement in the sensitivity limits.
