The Muon Magnetic Moment and Supersymmetry

  title={The Muon Magnetic Moment and Supersymmetry},
  author={Dominik Stockinger},
The present review is devoted to the muon magnetic moment and its role in supersymmetry phenomenology. Analytical results for the leading supersymmetric oneand two-loop contributions are provided, numerical examples are given and the dominant tanβ sign(μ)/M SUSY behaviour is qualitatively explained. The consequences of the Brookhaven measurement are discussed. The 2σ deviation from the Standard Model prediction implies preferred ranges for supersymmetry parameters, in particular upper and lower… 

Large muon (g − 2) with TeV-scale SUSY masses for tan β → ∞

A bstractThe muon anomalous magnetic moment aμ is investigated in the MSSM for tan β → ∞. This is an attractive example of radiative muon mass generation with completely different qualitative

Two-loop corrections to the muon magnetic moment from fermion/sfermion loops in the MSSM: detailed results

A bstractRecently, 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 even

Electric and anomalous magnetic dipole moments of the muon in the MSSM

We study the electric dipole moment (EDM) and the anomalous magnetic dipole moment (MDM) of the muon in the CP-violating Minimal Supersymmetric extension of the Standard Model (MSSM). We take into

Mixed modulus and anomaly mediation in light of the muon g − 2 anomaly

Abstract The new measurement of the anomalous magnetic moment of muon at the Fermilab Muon g− 2 experiment has strengthened the significance of the discrepancy between the standard model prediction

Prospects for Slepton Searches in Future Experiments

Muon g-2 anomaly, which is mismatch between the theoretical and the experimental values of the anomalous magnetic moment of muons, provides a sensitive probe of new physics. In SUSY, if masses of the

On the role of chirality flips for the muon magnetic moment and its relation to the muon mass

The muon mass and the anomalous magnetic moment a μ are quantities which require chirality flips, i.e., transitions between left- and right-handed muons. Muon chirality flips are connected to

Explaining muon g − 2 data in the μνSSM

We analyze the anomalous magnetic moment of the muon g − 2 in the μνSSM. This R-parity violating model solves the μ problem reproducing simultaneously neutrino data, only with the addition of

Understanding the correlation between (g − 2)μ and μ → eγ in the MSSM

A bstractThe supersymmetric contributions to the muon anomalous magnetic moment aμ and to the decay μ → eγ are given by very similar Feynman diagrams. Previous works reported correlations in specific

Supersymmetric SU(5) grand unification for a post Higgs boson era

A bstractWe investigate models of supersymmetric grand unification based on the gauge group SU(5). We consider models with non-universal gaugino masses and confront them with low energy constraints,



Muon Anomalous Magnetic Moment, Two-Higgs-Doublet Model, and Supersymmetry

The recent measurement of the muon anomalous magnetic moment ashows a 2.6� deviation from the standard model value. We show that it puts strong constraints on the parameter space of the two-Higgs

Superconservative interpretation of muon g-2 results applied to supersymmetry

The recent developments in theory and experiment related to the anomalous magnetic moment of the muon are applied to supersymmetry. We follow a very cautious course, demanding that the supersymmetric

Implications of muon anomalous magnetic moment for supersymmetric dark matter.

The anomalous magnetic moment of the muon is measured to be in conflict with the standard model prediction with an excess of 2.6sigma and at 95% confidence level it imposes an upper bound of 500 GeV on the neutralino mass and forbids Higgsinos as being the bulk of cold dark matter.

Supersymmetry and the anomalous anomalous magnetic moment of the muon.

The recently reported measurement of the muon's anomalous magnetic moment differs from the standard model prediction by 2.6 sigma, and model-independent upper bounds on the masses of observable supersymmetric particles are derived.
