Weak Corrections to Associated Higgs-Bottom Quark Production

TL;DR

This paper calculates weak corrections to Higgs production with bottom quarks, showing they are negligible at Tevatron energies but significant (~18%) at high Higgs masses (~1 TeV) at the LHC.

Contribution

It derives the weak corrections to bg -> bH process and introduces an accurate

Findings

Corrections are negligible at Tevatron for M_H < 200 GeV.

Weak corrections are small at LHC for M_H < 500 GeV.

Corrections reach about 18% for M_H ~ 1 TeV at 10 TeV energy.

Abstract

In models with an enhanced coupling of the Higgs boson to the bottom quark, the dominant production mechanism in hadronic collisions is often the partonic sub-process, bg ->bH. We derive the weak corrections to this process and show that they can be accurately approximated by an "Improved Born Approximation". At the Tevatron, these corrections are negligible and are dwarfed by PDF and scale uncertainties for M_H < 200 GeV. At the LHC, the weak corrections are small for M_H < 500 GeV. For large Higgs boson masses, the corrections become significant, and are ~18% for M_H ~ 1 TeV at E_CM=10 TeV.
