Electroweak fermion-loop contributions to the muon anomalous magnetic moment.
The two-loop electroweak corrections to the anomalous magnetic moment of the muon, generated by fermionic loops, are calculated. An interesting role of the top quark in the anomaly cancellation is observed. New corrections, including terms of order Gμαm 2 t , are computed and a class of diagrams previously thought to vanish are found to be important. The total fermionic correction is −(23±3)×10...
متن کاملElectroweak 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...
متن کاملHadronic 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...
متن کاملHadronic loop corrections to the muon anomalous magnetic moment.
The dominant theoretical uncertainties in both the anomalous magnetic moment of the muon and the value of the electromagnetic coupling at the Z scale, M(Z), arise from their hadronic contributions. Since these will ultimately dominate the experimental errors, we study the correlation between them, as well as with other fundamental parameters. To this end we present analytical formulas for the Q...
متن کاملSupersymmetric two-loop contributions to the anomalous magnetic moment of the muon
Recent results of two interesting classes of supersymmetric two-loop contributions to (g − 2)μ are presented. Two-loop diagrams involving a closed sfermion loop can amount to 5 × 10 or almost one standard deviation of the current experimental uncertainty, and two-loop diagrams with a closed chargino/neutralino loop can be similarly large. The dependence of these two classes on the unknown super...
