Hadronic Contributions to the Muon $g-2$ and Low-Energy QCD

arXiv:hep-ph/9311316 · doi:10.1016/0370-2693(94)91114-2

Abstract

The contributions to the muon anomalous magnetic moment from hadronic vacuum polarization and from hadronic light-by-light scattering are reexamined within the frame work of chiral perturbation theory; the $1/N_c$-expansion; and the extended Nambu Jona-Lasinio model of low-energy QCD.
