Higgs-photon associated production at hadron colliders

Abstract

We present cross sections for the reactions p pbar --> H gamma and pp --> Hγarising from the subprocess q qbar --> H gamma. The calculation includes the complete one-loop contribution from all light quarks as well as the tree contributions from light quarks and c and b quarks. These are the main sources of Higgs-photon associated production at hadron colliders. At Tevatron energies, the cross section is typically between 0.1fb and 1 fb for 80 Gev < m_H < 160 GeV, and at LHC energies it exceeds about 2 fb over the same range of m_H. While substantial, these cross sections are not large enough to produce a signal which is discernable above the backgrounds from q qbar-->b bbar gamma and gg-->b bbar gamma.
