چکیده
The Higgs-mass dependence of the two-loop contributions to muon decay is analyzed at the two-loop level. Exact results are given for the Higgsdependent two-loop corrections associated with the fermions, i.e. no expansion in the top-quark and the Higgs-boson mass is made. The remaining theoretical uncertainties in the Higgs-mass dependence of ∆r are discussed. 1 Contribution to the proceedings of the International Europhysics Conference on High-Energy Physics, Jerusalem, Israel, August 19–26, 1997. 710: Sensitivity of Two-Loop Corrections to Muon Decay to the Higgs-Boson Mass GeorgWeiglein ([email protected]) Institut für Theoretische Physik, Universität Karlsruhe, 76128 Karlsruhe, Germany Abstract.

The Littlest Higgs Model and One-Loop Electroweak Precision Constraints
We present in this talk the one-loop electroweak precision constraints in the Littlest Higgs model, including the logarithmically enhanced contributions from both fermion and scalar loops. We find the one-loop contributions are comparable to the tree level corrections in some regions of parameter space. A low cutoff scale is allowed for a non-zero triplet VEV. Constraints on various other param...
متن کاملMuon Decay to One Loop Order in the Left-Right Symmetric Model
One loop corrections to the muon decay are studied in a popular and self-consistent version of the Left-Right symmetric model. It is shown quantitatively, that the corrections do not split into those that come from the Standard Model sector, and some decoupling terms. For a heavy Spontaneous Symmetry Breaking (SSB) scale of the order of a least 1 TeV, the contributions from the top quark have a...
متن کاملTwo Loop Electroweak Bosonic Corrections to the Muon Decay Lifetime
The muon decay lifetime (τμ) has been used for long as an input parameter for high precision predictions of the Standard Model (SM). It allows for an indirect determination of the mass of the W boson (MW ), which suffers currently from a large experimental error of 33 MeV [1], one order of magnitude worse than that of the Z boson mass (MZ). A reduction of this error by LHC to 15 MeV [2] and by ...
متن کاملTo the Decay of an Intermediate–mass Higgs Boson into Two Photons∗
The QCD correction of O(α s ) to the decay of the Standard Model Higgs boson into two photons is presented. We consider the contribution coming from diagrams with a heavy top quark as virtual particle. The first three terms of the expansion in the inverse top mass is calculated. Expressing the result through the on-shell top mass Mt, we find large coefficients for the power-suppressed terms whe...

The two-loop electroweak bosonic correction to the muon lifetime and the M W –M Z interdependence is computed using analytical methods of asymptotic expansion. Combined with previous calculations this completes the full two-loop correction to ∆r in the Standard Model. The shift to the prediction of W-boson mass due to two-loop bosonic corrections does not exceed 1 MeV for the range of the Higgs...
