The Muon Magnetic Moment and Supersymmetry
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...
متن کاملMuon anomalous magnetic moment from effective supersymmetry
Abstract We present a detailed analysis on the possible maximal value of the muon (g− 2)μ ≡ 2aμ within the context of effective SUSY models with R parity conservation. First of all, the mixing among the second and the third family sleptons can contribute at one loop level to the aSUSY μ and τ → μγ simultaneously. One finds that the aSUSY μ can be as large as (10 − 20) × 10−10 for any tan β, imp...
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...
متن کاملUpdated Implications of the Muon Anomalous Magnetic Moment for Supersymmetry
We re-examine the bounds on supersymmetric particle masses in light of the new E821 data on the muon anomalous magnetic moment and the revised theoretical calculations of its hadronic contributions. Given that the current experimental excess is only about 1.9σ, there is no strong evidence for new physics. However, if one interprets the excess as coming from supersymmetry, one can obtain bounds ...
متن کاملImplications of the Muon Anomalous Magnetic Moment for Supersymmetry
We re-examine the bounds on supersymmetric particle masses in light of the E821 data on the muon anomalous magnetic moment, aμ. We confirm, extend and supersede previous bounds. In particular we find (at 1σ) no lower limit on tan β or upper limit on the chargino mass implied by the data at present, but at least 4 sparticles must be lighter than 700 to 820GeV and at least one sparticle must be l...
