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, $a_{I^} ¼$ , updating the first White Paper (WP20) [1]. The pure QED and electroweak contri…

Time-kernel for lattice determinations of NLO hadronic vacuum polarization contributions to the muon $g$ - $2$

Elisa Balzani, Stefano Laporta, Massimo Passera

We study the time-momentum representation of the kernel needed to compute hadronic vacuum polarization contributions to the muon $g$ - $2$ in the space-like region at next-to-leading…

Dimensional Regularization and Two-Loop Vacuum Polarization Operator: Master Integrals, Analytic Results and Energy Shifts

S. Laporta, U. D. Jentschura

We present a complete reevaluation of the irreducible two-loop vacuum-polarization correction to the photon propagator in quantum electrodynamics, i.e. with an electron-positron pa…
