Top quark loop corrections to the neutral Higgs boson production at the Fermilab Tevatron

摘要

We calculate the O(alpha m(t)(2) /m(w)(2) ) corrections arising from diagrams involving the top-quark loops to the light neutral Higgs boson production via q (q) over bar --> 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.
