The full electroweak Standard Model prediction for (g-2) of the muon and improvements on the MSSM prediction
H. G. Fargnoli, C. Gnendiger, S. Passehr +2
Recent progress on the (g-2)_μprediction is presented. In the SM, the Higgs-boson mass dependent contributions have been evaluated exactly up to the two-loop level and consistently…
Two-Loop Corrections to the Muon Magnetic Moment from Fermion/Sfermion Loops in the MSSM: Detailed Results
Helvecio Fargnoli, Christoph Gnendiger, Sebastian Paßehr +2
Recently, first results were presented for two-loop corrections to the muon (g-2) from fermion/sfermion loops in the MSSM. These corrections were shown to be generally large and ev…
Renormalization of vacuum expectation values in spontaneously broken gauge theories: Two-loop results
Marcus Sperling, Dominik Stöckinger, Alexander Voigt
We complete the two-loop calculation of beta-functions for vacuum expectation values (VEVs) in gauge theories by the missing O(g^4)-terms. The full two-loop results are presented f…
The electroweak contributions to (g-2)_μ after the Higgs boson mass measurement
C. Gnendiger, D. Stöckinger, H. Stöckinger-Kim
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…
Renormalization of vacuum expectation values in spontaneously broken gauge theories
Marcus Sperling, Dominik Stöckinger, Alexander Voigt
We compute one-loop and two-loop beta-functions for vacuum expectation values (VEVs) in gauge theories. In R_xi gauge the VEVs renormalize differently from the respective scalar fi…
