Study of VLVL to t tbar at the ILC Including O(alphas) QCD Corrections

Abstract

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 WL WL to t tbar and ZL ZL to t tbar might provide hints of new physics. In this paper we present results of O(alphas) QCD corrections to VLVL to t tbar scattering at the 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 to t tbar.
