Higgs production at the Tevatron: theoretical predictions and uncertainties

Abstract

We present an update of the theoretical predictions for the production cross sections of the Standard Model Higgs boson at the Tevatron collider in the gluon‐gluon fusion channel, including all relevant higher order QCD and electroweak corrections in perturbation theory. A thorough analysis of the theoretical uncertainties affecting these predictions will then follow: the scale uncertainty, the uncertainties associated with the PDF and the errors on the value of the strong coupling αS and the uncertainties related to the use of an effective field theory in the gluon‐gluon channel. The combined theoretical uncertainty is found to be large and will impact the Tevatron Higgs exclusion bound.
