The g-factor of the muon bound in a nuclear potential — •Bastian Sikora, Nikolay Belov, Zoltán Harman, and Christoph H. Keitel — Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, 69117 Heidelberg, Germany

We present the theory of the g-factor of the muon bound in a nuclear potential. One-loop self-energy and vacuum polarization corrections are included, taking into account the interaction with the nuclear potential exactly. Moreover, we incorporate finite nuclear size and finite nuclear mass corrections.

The theory of the bound-muon g-factor, combined with possible future experiments involving bound muons can be used in principle to test quantum electrodynamics in stronger electric fields than possible with bound electrons. Furthermore, since contributions due to nuclear effects are large for bound muons, nuclear parameters can be determined by comparing the theoretical and experimental bound-muon g-factor.
