Demonstration of deuterium's enhanced sensitivity to symmetry violations governed by the Standard-Model Extension
Amit Nanda, Daniel Comparat, Olivier Dulieu +5
We have performed hyperfine spectroscopy of two transitions in ground-state deuterium and searched for violations of CPT and Lorentz symmetry that would manifest as sidereal variat…
Towards a Study of Low Energy Antiproton Annihilations on Nuclei
Viktoria Kraxberger, Marcus Bumbar, Angela Gligorova +30
A study of antiproton annihilations at rest on thin solid targets is underway at the ASACUSA facility, which now features a dedicated beam line for slow extraction at 250 eV. The e…
GRASIAN: Shaping and characterization of the cold hydrogen and deuterium beams for the forthcoming first demonstration of gravitational quantum states of atoms
Carina Killian, Philipp Blumer, Paolo Crivelli +9
A low energy particle confined by a horizontal reflective surface and gravity settles in gravitationally bound quantum states. These gravitational quantum states (GQS) were so far…
Antiproton annihilation at rest in thin solid targets and comparison with Monte Carlo simulations
Claude Amsler, Horst Breuker, Marcus Bumbar +33
The mechanism of antiproton-nucleus annihilation at rest is not fully understood, despite substantial previous experimental and theoretical work. In this study we used slow extract…
CPT and Lorentz symmetry tests with hydrogen using a novel in-beam hyperfine spectroscopy method applicable to antihydrogen experiments
Lilian Nowak, Chloe Malbrunot, Martin C. Simon +8
We present a Rabi-type measurement of two ground-state hydrogen hyperfine transitions performed in two opposite external magnetic field directions. This puts first constraints at t…
An atomic hydrogen beam to test ASACUSA's apparatus for antihydrogen spectroscopy
Martin Diermaier, Peter Caradonna, Bernadette Kolbinger +7
The ASACUSA collaboration aims to measure the ground state hyperfine splitting (GS-HFS) of antihydrogen, the antimatter pendant to atomic hydrogen. Comparisons of the corresponding…
