Anomalous magnetic moment of muon and L-violating Supersymmetric Models
We consider L-violating Supersymmetric Models to explain the recent muon gμ − 2 deviation from the Standard Model. The order of trilinear L-violating couplings which we require also generate neutrino mass which is somewhat higher than expected unless one considers highly suppressed L − R mixing of sfermions. However, without such fine tuning for sfermions it is possible to get appropriate muon ...
متن کاملSupersymmetric Model of Muon Anomalous Magnetic Moment and Neutrino Masses
We propose the novel lepton-number relationship Lτ = Le + Lμ, which is uniquely realized by the interaction (ν̂eμ̂ − êν̂μ)τ̂ c in supersymmetry and may account for a possibly large muon anomalous magnetic moment. Neutrino masses (with bimaximal mixing) may be generated from the spontaneous and soft breaking of this lepton symmetry. In the minimal standard model of particle interactions, the 3 lepto...
متن کاملMuon anomalous magnetic dipole moment in supersymmetric theories
We study the muon anomalous magnetic dipole moment in supersymmetric theories. The impact of the recent Brookhaven E821 experimental measurement on both modelindependent and model-dependent supersymmetric parameter spaces is discussed in detail. We find that values of tanβ as low as 3 can be obtained while remaining within the E821 one-sigma bound. This requires a light smuon; however, we show ...
متن کاملThe Bnl Muon Anomalous Magnetic Moment Measurement
The E821 experiment at Brookhaven National Laboratory is designed to measure the muon magnetic anomaly, aμ, to an ultimate precision of 0.4 parts per million (ppm). Because theory can predict aμ to 0.6 ppm, and ongoing efforts aim to reduce this uncertainty, the comparison represents an important and sensitive test of new physics. At the time of this Workshop, the reported experimental result f...
متن کاملSupersymmetry 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. We examine the implications of this discrepancy for supersymmetry. Deviations of the reported magnitude are generic in supersymmetric theories. Based on the new result, we derive model-independent upper bounds on the masses of observable supersymmetric particles. We...
