The anomalous magnetic moment of the muon in the Standard Model: an update

R. Aliberti, T. Aoyama, E. Balzani +232

We present the current Standard Model (SM) prediction for the muon anomalous magnetic moment, $a_{μ}$ , updating the first White Paper (WP20) [1]. The pure QED and electroweak contrib…

Data-driven results for light-quark connected and strange-plus-disconnected hadronic $g - 2$ short- and long-distance windows

Genessa Benton, Diogo Boito, Maarten Golterman +3

A key issue affecting the attempt to reduce the uncertainty on the Standard Model prediction for the muon anomalous magnetic moment is the current discrepancy between lattice-QCD a…

Data-driven evaluations of Euclidean windows to scrutinize hadronic vacuum polarization

G. Colangelo, A. X. El-Khadra, M. Hoferichter +4

In this paper, we discuss how windows in Euclidean time can be used to isolate the origin of potential conflicts between evaluations of the hadronic-vacuum-polarization (HVP) contr…

Prospects for precise predictions of $a_{μ}$ in the Standard Model

G. Colangelo, M. Davier, A. X. El-Khadra +79

We discuss the prospects for improving the precision on the hadronic corrections to the anomalous magnetic moment of the muon, and the plans of the Muon $g - 2$ Theory Initiative to…

The muon $g$ -2 and $Δ α$ connection

Alexander Keshavarzi, William J. Marciano, Massimo Passera +1

The discrepancy between the Standard Model theory and experimental measurement of the muon magnetic moment anomaly, $a_{μ} = (g_{μ} - 2) /2$ , is connected to precision electrowea…
