====== TTP99-12 Axial Contributions at the Top Threshold ======
 
 
   <hidden TTP99-12  Axial Contributions at the Top Threshold > 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.
