摘要：
We calculate the O(alpha(ew)) electroweak radiative corrections to e(+)e(-) --> t (t) over barh at a electron-positron linear collider (LC) in the standard model. We analyze the dependence of the O(alpha(ew)) corrections on the Higgs boson mass m(h), and colliding energy roots, and find that the corrections significantly decrease or increase the Born cross section depending on the colliding energy. The numerical results show that the O(alpha(ew)) relative correction is strongly related to the Higgs boson mass when roots = 500 GeV, and for m(h) = 150 GeV the relative correction ranges from -31.3% to 2.3% as the increment of the colliding energy from 500 GeV to 2 TeV.
