Theory of the bound-muon g-factor — •Bastian Sikora, Zoltán Harman, Jacek Zatorski, and Christoph H. Keitel — Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, 69117 Heidelberg, Germany

The theory of the g-factor of the muon bound in a nuclear potential is presented. We include one-loop quantum electrodynamic corrections with the interaction with the nuclear potential taken into account to all orders, and finite nuclear size effects. Similarly to the recent high-precision determination of the electron mass [1], the theory of the bound-muon g-factor, combined with possible future experiments with muons bound in a nuclear potential, can be used in principle to determine physical constants with high precision. Furthermore, since nuclear effects are larger in systems with bound muons, nuclear parameters such as nuclear radii can be extracted to high precision from a comparison of the theoretical and experimental bound-muon g-factor.
