The anomalous magnetic moment of the muon

The 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...

Supersymmetry 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...

Hadronic contributions to the anomalous magnetic moment of the muon.

We present a new, completely revised calculation of the muon anomalous magnetic moment, aµ = (gµ − 2)/2, comparing it with the more recent experimental determination of this quantity; this furnishes an important test of theories of strong, weak and electromagnetic interactions. These theoretical and experimental determinations give the very precise numbers, In the theoretical evaluations, the f...

The Muon Anomalous Magnetic Moment - Significance of the New Measurement

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...
