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…

Record accumulation of antiprotons in a Penning-Malmberg Trap and their preparation for improved production of antihydrogen beams

B. Lee, B. Kim, P. Adrich +35

CERN's AD/ELENA ``antimatter factory'' - unique worldwide - serves several experiments, all of which use electromagnetic traps to accumulate antiprotons for fundamental science. Th…

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 antiprotonic…

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…

Positron production using a 9 MeV electron linac for the GBAR experiment

M. Charlton, J. J. Choi, M. Chung +67

For the GBAR (Gravitational Behaviour of Antihydrogen at Rest) experiment at CERN's Antiproton Decelerator (AD) facility we have constructed a source of slow positrons, which uses…
