چکیده

We report the result of our calculation of the complete tenth-order QED terms of the muon g-2. Our result is a(μ)((10))=753.29 (1.04) in units of (α/π)(5), which is about 4.5 s.d. larger than the leading-logarithmic estimate 663(20). We also improve the precision of the eighth-order QED term of a(μ), obtaining a(μ)((8))=130.8794 (63) in units of (α/π)(4). The new QED contribution is a(μ)(QED)=116,584,718,951 (80)×10(-14), which does not resolve the existing discrepancy between the standard-model prediction and measurement of a(μ).

 The g-factor of the charged leptons has always been considered by many physicists, both experimentaly as well as theoretically. In fact the electron and muon g-factor play the main role in testing the QED as well as the standard model. Meanwhile, there is a discrepancy between the standard model prediction of the muon anomalies magnetic moment and its experimental determination as large as (25...

Tenth-order QED contribution to the electron g-2 and an improved value of the fine structure constant.

This letter presents the complete QED contribution to the electron g-2 up to the tenth order. With the help of the automatic code generator, we evaluate all 12,672 diagrams of the tenth-order diagrams and obtain 9.16 (58)(α/π)(5). We also improve the eighth-order contribution obtaining -1.9097 (20)(α/π)(4), which includes the mass-dependent contributions. These results lead to a(e)(theory)=1,15...

Results and Future Prospects for Muon (g − 2) *

Spin physics had its beginnings in the famous experiments of Stern and Gerlach, which eventually resulted in the postulation of spin by Goudsmit and Uhlenbeck. The Stern-Gerlach experiment told us that the g-value of the electron was 2, but we now know that because of radiative corrections, the g-value of the leptons is slightly greater than 2, the lowest-order contribution being α/π, where α i...

Electroweak corrections to the muon anomalous magnetic moment.

We employ an effective Lagrangian approach to derive the leading-logarithm two-loop electroweak contributions to the muon anomalous magnetic moment, a µ. We show that these corrections can be obtained using known results on the anomalous dimensions of composite operators. We confirm the result of Czarnecki et al. for the bosonic part and present the complete sin 2 θ W dependence of the fermioni...

A charged particle with spin ~s has a magnetic moment ~μs = gs(e/2m)~s; an anomaly a ≡ (gs − 2)/2; and μ = (1+a)eh̄/2m; where gs is the gyromagnetic ratio, and the latter expression is what one finds in the Particle Data Tables.[1] The g-value is exactly 2 for a point-like fermion in the Dirac equation, but radiative corrections give rise to a non-zero value for the anomaly a. The lowest order (...
