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…

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…
