Abstract
We investigate the possibilities of studying new physics in various processes of $t-quark$ production using kinematical distributions of the secondary lepton coming from decay of $t$ quarks. We show that the angular distributions of the secondary lepton are insensitive to the anomalous $tbW$ vertex and hence are pure probes of new physics in a generic process of $t-quark$ production. The effects of $t$ polarization on the distributions of the decay lepton are demonstrated for top-pair production process at a \gamma \gamma -collider mediated by a heavy Higgs boson.
