The Higgs-boson mass used to be the only unknown input parameter of the electroweak contributions toin the Standard Model. It enters at the two-loop level in diagrams with, e.g., top loops,, orexchange. We reevaluate these contributions, providing analytic expressions and exact numerical results for the Higgs-boson mass recently measured at the LHC. Our final result for the full Standard Model electroweak contributions is, where the remaining theory error comes from unknown three-loop contributions and hadronic uncertainties.
