Study of VLVL→tt̄ at the International Linear Collider including O(αs) QCD corrections
In the event that the Higgs mass is large or that the electroweak interactions are strongly interacting at high energy, top-quark couplings to longitudinal components of the weak gauge bosons could offer important clues to the underlying dynamics. It has been suggested that precision measurements of WLWL→tt̄ and ZLZL→tt̄ might provide hints of new physics. In this paper we present results for O(αs) QCD corrections to VLVL→tt̄ scattering at the International Linear Collider (ILC). We find that corrections to cross sections can be as large as 30% and must be accounted for in any precision measurement of VV→tt̄.
