Analytic expressions for the angular distributions of the b-quarks
associated with single t-quark production in ppΛββWββtbΛβbbΛW and of the leptons from the subsequent decay WβlΞ½ are
obtained in the laboratory system. CP violation in the t-production vertex is
assumed. Different angular and total cross section CP violating asymmetries are
considered. Relations testing CP violation solely in the t-decay vertex are
also obtained. A numerical analysis is performed in the MSSM with a CP
violating phase of the trilinear coupling At~β. The asymmetries are
typically of the order 10β3 - 10β4.Comment: The numerical results are corrected and some changes that meet the
requirements of Phys. Rev. D are mad
