    Analytic expressions for the angular distributions of the bb-quarks associated with single tt-quark production in ppˉ→W∗→tbˉ→bbˉWp \bar p \to W^* \to t \bar b \to b \bar b W and of the leptons from the subsequent decay W→lνW \to l\nu are obtained in the laboratory system. CP violation in the tt-production vertex is assumed. Different angular and total cross section CP violating asymmetries are considered. Relations testing CP violation solely in the tt-decay vertex are also obtained. A numerical analysis is performed in the MSSM with a CP violating phase of the trilinear coupling At~A_{\tilde t}. The asymmetries are typically of the order 10−310^{-3} - 10−410^{-4}.Comment: The numerical results are corrected and some changes that meet the requirements of Phys. Rev. D are mad
