QCD Corrections to Associated Higgs Boson-Heavy Quark Production

Abstract

We compute the O(alpha_s) QCD corrections to the inclusive process e^+e^- --> t \bar t h. Although the total rate is small, it has a distinctive experimental signature and can potentially be used to measure the top quark-Higgs boson Yukawa coupling. The QCD corrections increase the rate by a factor of roughly 1.5 for e^+e^- --> t \bar t h at sqrt(s)=500 GeV and Mh=100 GeV. At sqrt(s)=1 TeV, the corrections are small.
