| Title: | Stringent Test of QED using Highly Charged Tin |
| Quantum electrodynamics is the best-tested fundamental theory. It is ubiquitous and contributes to almost all fundamental processes. The Standard Model of particle physics is still incomplete and requires further research. It is therefore important to deepen the understanding of the most accessible processes. Quantum electrodynamics must therefore be tested in all its facets and its validity verified in extreme situations in order to be able to draw conclusions about our Universe. To this end, three high-precision g-factor measurements on different charge states of highly charged tin are presented here, testing the theory in the extreme electric field around the nucleus.In the Penning-Trap apparatus ALPHATRAP, the g-factor of hydrogen-like, lithium-like and boron-like tin was determined to 5 parts-per-billion, and is compared to the ab initio theory prediction. The hydrogen-like measurement stringently probes the electron-nucleus interaction, while the lithium-like and the boron-like measurements test the electron-electron interaction as well. |
