A 16 Parts per Trillion Comparison of the Antiproton-to-Proton q/m Ratios
M. J. Borchert, J. A. Devlin, S. E. Erlewein +20
The Standard Model (SM) of particle physics is both incredibly successful and glaringly incomplete. Among the questions left open is the striking imbalance of matter and antimatter…
Sympathetic cooling of a trapped proton mediated by an LC circuit
M. Bohman, V. Grunhofer, C. Smorra +18
Efficient cooling of trapped charged particles is essential to many fundamental physics experiments, to high-precision metrology, and to quantum technology. Until now, sympathetic…
Towards Sympathetic Cooling of Single (Anti-)Protons
T. Meiners, M. Niemann, J. Mielke +5
We present methods to manipulate and detect the motional state and the spin state of a single antiproton or proton which are currently under development within the BASE (Baryon Ant…
Cryogenic Penning-Trap Apparatus for Precision Experiments with Sympathetically Cooled (anti)protons
M. Niemann, T. Meiners, J. Mielke +17
Current precision experiments with single (anti)protons to test CPT symmetry progress at a rapid pace, but are complicated by the need to cool particles to sub-thermal energies. We…
Measurement of the Principal Quantum Number Distribution in a Beam of Antihydrogen Atoms
B. Kolbinger, C. Amsler, S. Arguedas Cuendis +35
The ASACUSA (Atomic Spectroscopy And Collisions Using Slow Antiprotons) collaboration plans to measure the ground-state hyperfine splitting of antihydrogen in a beam at the CERN An…
Direct limits on the interaction of antiprotons with axion-like dark matter
C. Smorra, Y. V. Stadnik, P. E. Blessing +18
Astrophysical observations indicate that there is roughly five times more dark matter in the Universe than ordinary baryonic matter, with an even larger amount of the Universe's en…
