Accurate prediction of electroweak observables and impact on the Higgs mass bound

Abstract

I discuss the importance of the $O(g^4{m}_t^2/{\text{mw}}^2)$ corrections to the effective electroweak angle and Mw in the indirect determination of the Higgs mass. I emphasize the rôle of a very precise Mw measurement on the Mh estimate.
