Abstract

We calculate the O(αew) electroweak radiative corrections to e+e−→tt̄h at a electron–positron linear collider (LC) in the standard model. We analyze the dependence of the O(αew) corrections on the Higgs boson mass mh and colliding energy s, 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(αew) relative correction is strongly related to the Higgs boson mass when s=500 GeV, and for mh=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.
