Understanding the muon anomalous magnetic moment in light of a flavor symmetry-based Minimal Supersymmetric Standard Model

چکیده
We investigate whether the Minimal Supersymmetric Standard Model with the scalar masses of the third generation distinct from the first two, in order to be able to accommodate the muon anomalous magnetic moment, is consistent with the latest results from LHCb, direct collider bounds from ATLAS and CMS. In particular, we show that this class of models allows for satisfying both the constraints from the muon (g − 2)μ experiment and various bounds from the LHC. In addition, such models can also explain the observed dark matter relic density.

Supersymmetric Relations Among Electromagnetic Dipole Operators
Supersymmetric contributions to all leptonic electromagnetic dipole operators have essentially identical diagramatic structure. With approximate slepton universality this allows the muon anomalous magnetic moment to be related to the electron electric dipole moment in terms of supersymmetric phases, and to radiative flavor changing lepton decays in terms of small violations of slepton universal...

We describe here SuperIso which is a public program for evaluation of flavor physics observables as well as the muon anomalous magnetic moment and the dark matter relic density in the Standard Model (SM), general two-Higgs-doublet model (2HDM), minimal supersymmetric Standard Model (MSSM) and next to minimal supersymmetric Standard Model (NMSSM). A few examples of the analysis and the results o...

We present the results of the influence of the minimal supersymmetric standard model extended by an additional Higgs singlet N, with vacuum expectation value vN , on the anomalous magnetic moment of the muon. This gives different mass matrices for the charginos and neutralinos, which are taken into account within the relevant penguin diagrams leading to a contribution ∆aμ to the anomalous magne...

The status of the constrained minimal supersymmetric standard model (CMSSM) will be discussed in light of our current understanding of the relic density after WMAP. A global likelihood analysis of the model is performed including data from direct Higgs searches, global fits to electroweak data, b → sγ, the anomalous magnetic moment of the muon, as well as the cosmological relic density. Also co...
متن کاملMuon anomalous magnetic dipole moment in the minimal supersymmetric standard model.
The muon anomalous magnetic dipole moment (MDM) is calculated in the framework of the minimal supersymmetric standard model (MSSM). In this paper, we discuss how the muon MDM depends on the parameters in MSSM in detail. We show that the contribution of the superparticle-loop becomes significant especially when tan β is large. Numerically, it becomes O(10−8 − 10−9) in a wide parameter space, whi...
