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/\mw^2) corrections to the effective electroweak angle and Mw in the indirect determination of the Higgs mass. I emphasize the r\^ole of a very precise Mw measurement on the Mh estimate.Comment: 9 pages, LaTex, uses appb.sty.
