Zusammenfassung:(ProQuest: ... denotes formulae and/or non-USASCII text omitted; see image) We present the full ... electroweak radiative corrections to the process ... at the International Linear Collider (ILC). The computation is performed with the help of the GRACE-Loop system. We present the total cross-section and the top quark forward-backward asymmetry (A ^sub FB^) as a function of the center-of-mass energy and compare them with the process ... We find that the value of A ^sub FB^ in ... production is larger than A ^sub FB^ in ... production. It is an important result for the measurement of the top quark forward-backward asymmetry at the ILC. Applying a structure function method, we also subtract the QED correction to gain the genuine weak correction in both the [alpha] scheme and the G ^sub [mu]^ scheme (...). We obtain numerical values for ... which are changing from 2 % to -24 % when we vary the center-of-mass energy from 360 GeV to 1 TeV.
