CP Nonconservation in $p\bar{p}\to t\bar{b}X$ at the Tevatron

Abstract

The reaction $p\bar{p}\to t\bar{b}X$ is found to be rather rich in exhibiting several different types of CP asymmetries. The spin of the top quark plays an important role. Asymmetries are related to form factors arising from radiative corrections of the $tbW$ production vertex due to non-standard physics. As illustrations, effects are studied in two Higgs Doublet Models and in Supersymmetric Models; asymmetries up to a few percent may be possible.
