Leading electroweak corrections to the neutral Higgs boson production at the Fermilab tevatron

We calculate the leading electroweak corrections to the light neutral Higgs boson production via q (q) over bar' --> W H at the Fermilab Tevatron in both the standard model and the minimal supersymmetric model, which arise from the top-quark and Higgs boson loop diagrams. We found that the leading electroweak corrections can exceed the QCD corrections for favorable values of the parameters in the MSSM, but such corrections are only about -2% similar to -4% in the SM, which are much smaller than the QCD corrections. For the mass region of 90 < m(h0) < 120 GeV, the leading electroweak corrections can reach -20% for large tan beta, and these corrections may be observable at a high luminosity Tevatron; at the least, new constraints on the tan beta can be established.
