Muon 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 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...
متن کاملHadronic light-by-light scattering contribution to the muon anomalous magnetic moment from lattice QCD.
The most compelling possibility for a new law of nature beyond the four fundamental forces comprising the standard model of high-energy physics is the discrepancy between measurements and calculations of the muon anomalous magnetic moment. Until now a key part of the calculation, the hadronic light-by-light contribution, has only been accessible from models of QCD, the quantum description of th...
متن کاملThe Muon Anomalous Magnetic Moment: A Harbinger For “New Physics”
QED, Hadronic, and Electroweak Standard Model contributions to the muon anomalous magnetic moment, aμ ≡ (gμ − 2)/2, and their theoretical uncertainties are scrutinized. The status and implications of the recently reported 2.6 sigma experiment vs. theory deviation a μ − a μ = 426(165) × 10 are discussed. Possible explanations due to supersymmetric loop effects with mSUSY ≃ 55 √ tan β GeV, radiat...
