Brane Fluctuation and anomalous muon magnetic moment
We study the effects of extra dimensions on the muon anomalous magnetic moment with brane fluctuation. Since the coupling is naturally suppressed if brane fluctuation is considered by exponential softening factor for heavier states, the contribution from the whole Kaluza-Klein graviton tower is shown to be finite. The recent BNL E821 result is accomodated with D = 4 + δ dimensional gravitationa...
متن کاملMuon anomalous magnetic moment and leptoquark solutions
The recent measurement of the muon anomalous magnetic moment am shows a 2.6s deviation from the standard model value. We show that it puts an interesting bound on the mass of the second generation leptoquarks. To account for the data the leptoquark must have both leftand right-handed couplings to the muon. Assuming that the couplings have electromagnetic strength, the mass is restricted in the ...
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 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...
