摘要：

The effect of anomalous chromoelectric couplings of the gluon to the top quark are considered in e(+)e(-) --> t (t) over bar. The total cross section, as well as t and (t) over bar polarizations are calculated to order alpha(s) in the presence of the anomalous couplings. One of the two linear combinations of t and (t) over bar polarizations is CP even, while the other is CP odd. Limits that could be obtained at a future linear collider on CP-odd combinations of anomalous couplings are determined. (C) 1998 Elsevier Science B.V.
