| | <hidden TTP97-40 O(\alpha_s^2) Corrections to Top Quark Production at e^+e^- Colliders > In this article we evaluate mass corrections up to $O((m^2/q^2)^6)$ to the |
| | three-loop polarization function induced by an axial-vector |
| | current. Special emphasis is put on the evaluation of the singlet |
| | diagram which is absent in the vector case. As a physical application |
| | $O(\alpha_s^2)$ corrections to the production of top quarks at |
| | future $e^+e^-$ colliders is considered. It is demonstrated that for |
| | center of mass energies $\sqrt{s} >~ 500$ GeV the inclusion of the |
| | first seven terms into the cross section leads to a reliable |
| | description. |
