Abstract
The reaction <p(p)over bar>--><t(b)over barX> is found to be rather ri ch in exhibiting several different types of CP asymmetries. The spin o f the top quark plays an important role. Asymmetries are related to fo rm factors arising from radiative corrections of the tbW production ve rtex due to nonstandard physics. As illustrations, effects are studied in two Higgs doublet models and in supersymmetric models; asymmetries up to a few percent may be possible.
