Abstract
We calculate the O( αm t 2/ m W 2) corrections arising from diagrams involving the top-quark loops to the light neutral Higgs boson production via q q ̄ ′→WH at the Fermilab Tevatron in both the standard model and the minimal supersymmetric model. In contrast to the QCD correction which increases the tree-level cross section, the corrections imply a few percent reduction in the production cross section relative to the tree-level results.
