Two-loop light fermion contribution to Higgs production and decays
arXiv:hep-ph/0404071 · doi:10.1016/j.physletb.2004.06.063
Abstract
We compute the electroweak corrections due to the light fermions to the production cross section and to the partial decay widths and . We present analytic results for these corrections that are expressed in terms of Generalized Harmonic Polylogarithms. We find that for the gluon fusion production cross section and for the decay width the corrections are large in the Higgs mass region below 160 GeV where they reach up to 9% of the lowest order term. For the decay width the corrections for Higgs mass above 160 GeV can reach 10% of the lowest order term.
