Abstract
We review recent theoretical progress in the computation of radiative corrections beyond one loop within the standard model of electroweak interactions, in both the gauge and Higgs sectors. In the gauge sector, we discuss universal corrections of , , and , and those due to virtual -threshold effects, as well as specific corrections to of , and including finite-mb effects. We also present an update of the hadronic contributions to Δα. Theoretical uncertainties, other than those due to the lack of knowledge of MH and mt, are estimated. In the Higgs sector, we report on the corrections to including those which are specific for the mode, the corrections to including the finite-mq terms, and the corrections to Γ(H → gg).Keywords
