Bound-state QED test above the Schwinger limit with kaonic fluorine
F. Clozza, S. Manti, F. Sgaramella +35
Kaonic atoms, formed when a negatively charged kaon replaces an electron in an atomic orbit, provide access to bound-state quantum electrodynamics (BSQED) in electromagnetic fields…

Binding Energy of Muonic Beryllium: Perturbative versus All--Order Calculations
Shikha Rathi, Ulrich D. Jentschura, Paul Indelicato +1
We compute the ground-state binding energy of muonic Be in two ways: first, the fully perturbative treatment of the nuclear-size effect often employed in light systems, and sec…
