Abstract:
We study the impact of the two-loop electroweak corrections on the production of a Higgs boson
via gluon-fusion in proton-proton collisions at LHC energies. We discuss the prescritpion to include
the corrections to the hard scattering matrix element in the calculation of the hadronic cross-section
σ(p + p
→ H + X). Under the hypothesis of factorization of the electroweak corrections with respect to
the dominant soft and collinear QCD radiation, we observe an increase of the total cross-section from 4
to 8%, for mh
≤ 160 GeV. This increase is comparable with the present QCD uncertainties originating
from hard scattering matrix elements.
