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…
Sympathetic Cooling of Protons and Antiprotons with a Common Endcap Penning Trap
M. Bohman, A. Mooser, G. Schneider +12
We present an experiment to sympathetically cool protons and antiprotons in a Penning trap by resonantly coupling the particles to laser cooled beryllium ions using a common endcap…
Observation of individual spin quantum transitions of a single antiproton
C. Smorra, A. Mooser, M. Besirli +15
We report on the detection of individual spin quantum transitions of a single trapped antiproton in a Penning trap. The spin-state determination, which is based on the unambiguous…
Highly-sensitive superconducting circuits at ~700 kHz with tunable quality factors for image-current detection of single trapped antiprotons
H. Nagahama, G. Schneider, A. Mooser +14
We developed highly-sensitive image-current detection systems based on superconducting toroidal coils and ultra-low noise amplifiers for non-destructive measurements of the axial f…
BASE - The Baryon Antibaryon Symmetry Experiment
C. Smorra, K. Blaum, L. Bojtar +17
The Baryon Antibaryon Symmetry Experiment (BASE) aims at performing a stringent test of the combined charge parity and time reversal (CPT) symmetry by comparing the magnetic moment…
