Abstract

We calculate the correction to qq»tt» of order g2mt2MW2. This correction, proportional to the square of the Higgs-boson Yukawa coupling to the top quark, arises from loops of Higgs bosons and the scalar component of virtual vector bosons. The Yukawa correction to the total tt» production cross section at the Fermilab Tevatron in the standard Higgs model is found to be much less than the theoretical uncertainty in the cross section. However, in a two-Higgs-doublet model, Yukawa couplings are generally enhanced. The Yukawa correction can increase the total tt» production cross section in this model by as much as 20-35%, which is potentially observable at the Tevatron.
