Abstract.

We calculate the contributions of the axial current to top quark pair production in \(e^+ e^-\) annihilation at threshold. The QCD dynamics is taken into account by solving the Lippmann-Schwinger equation for the P wave production using the QCD potential up to two loops. We demonstrate that the dependence of the total and differential cross section on the polarization of the \(e^+\) and \(e^-\) beams allows for an independent extraction of the axial current induced cross section.
