Many-electron QED corrections to the g factor of lithiumlike ions

Abstract

A rigorous QED evaluation of the two-photon exchange corrections to the g factor of lithiumlike ions is presented. The screened self-energy corrections are calculated for the intermediate-$Z$ region and its accuracy for the high-$Z$ region is essentially improved in comparison with that of previous calculations. As a result, the theoretical accuracy of the g factor of lithiumlike ions is significantly increased. The theoretical prediction obtained for the g factor of ${}^{28}$Si${}^{11+}$ ${\mathrm{g}}_{\mathrm{th}}=2.000889892(8)$ is in an excellent agreement with the corresponding experimental value ${\mathrm{g}}_{\exp }=2.0008898899(21)$ [A. Wagner et al., Phys. Rev. Lett. 110, 033003 (2013)].
