Theory Framework for Medium-Mass Muonic Atoms
S. Rathi, I. A. Valuev, Z. Sun +4
We present a state-of-the-art theoretical approach for computing bound-state energies in muonic atoms, incorporating improved quantum electrodynamics effects and nuclear polarizati…
Shake-up and shake-off spectra in the electron capture decay of atomic Be
Mauro Guerra, Inwook Kim, Stephan Friedrich +33
The most stringent laboratory-based experimental limits on the existence of sub-MeV sterile neutrinos are currently set by decay spectroscopy of radioactive Be embedded into su…
All-Order Wichmann and Kroll Contribution in Heavy Electronic and Exotic Atoms
Jonas Sommerfeldt, Paul Indelicato
We present a theoretical study of the Wichmann and Kroll correction to the one-loop vacuum polarization (VP) to all-orders in . We consider electronic, muonic, and antiprotoni…
Towards Precision Spectroscopy of Antiprotonic Atoms for Probing Strong-field QED
Gonçalo Baptista, Shikha Rathi, Michael Roosa +26
PAX (antiProtonic Atom X-ray spectroscopy) is a new experiment with the aim to test strong-field quantum electrodynamics (QED) effects by performing high-precision x-ray spectrosco…
Few-electron highly charged muonic Ar atoms verified by electronic x rays
T. Okumura, T. Azuma, D. A. Bennett +40
Electronic x rays emitted by muonic Ar atoms in the gas phase were observed using a superconducting transition-edge-sensor microcalorimeter. The high-precision energy spectra p…
