Abstract: (APS)
The Higgs-boson mass used to be the only unknown input parameter of the electroweak contributions to (g-2)μ in the Standard Model. It enters at the two-loop level in diagrams with, e.g., top loops, W, or Z exchange. 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 (153.6±1.0)×10-11, where the remaining theory error comes from unknown three-loop contributions and hadronic uncertainties.
