CP violation in e(+)e(-)-> t(t)over-bar: Energy asymmetries and optimal observables of b and (b)over-bar quarks - art. no. 077503

The energy spectra of the b and (b)over-bar quarks in e(+)e(-)-->t(t)over-b ar with t-->bW ((t)over-bar-->(b)over-bar-W) are calculated assuming CP vio lation in the production process. Expressions for the corresponding CP viol ating asymmetries and optimal observables that determine the imaginary part s of the electric and weak dipole moment form factors of the top quark are derived. It is shown that polarization of the initial lepton beams is essen tial to disentangle Im d(gamma)(s) and Im d(Z)(s). Numerical results are gi ven in the minimal supersymmetric standard model with complex phases. [S055 6-2821(99)02507-2].
