Single-quark spin asymmetries in e+e−→tt and anomalous gluon couplings

The effect of anomalous chromoelectric couplings of the gluon to the top quark are considered in e+e−→tt. The total cross section, as well as t and t polarizations are calculated to order αs in the presence of the anomalous couplings. One of the two linear combinations of t and t 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.
