First measurement of the antihydrogen production cross section through the charge-exchange reaction of low-energy antiprotons with orthopositronium
GBAR Collaboration, P. Adrich, I. Belosevic +42
The GBAR experiment has measured the formation rate of antihydrogen from antiproton impact on a positronium cloud for antiproton kinetic energies of 4 and 6 keV. This is the first…
A determination of the backscattering probability of low-energy antiprotons
GBAR Collaboration, K. Park, E. Perez +42
It is commonly assumed that antiprotons impinging on a material surface annihilate promptly with the nuclei of the material. However, at kinetic energies of a few keV, this assumpt…
Antihydrogen formation dynamics in a multipolar neutral anti-atom trap
G. B. Andresen, W. Bertsche, P. D. Bowe +33
Antihydrogen production in a neutral atom trap formed by an octupole-based magnetic field minimum is demonstrated using field-ionization of weakly bound anti-atoms. Using our uniqu…
Production of Slow Protonium in Vacuum
N. Zurlo, M. Amoretti, C. Amsler +28
We describe how protonium, the quasi-stable antiproton-proton bound system, has been synthesized following the interaction of antiprotons with the molecular ion H in a nested…
Cold-Antimatter Physics
ATHENA Collaboration, M. Amoretti, C. Amsler +33
The CPT theorem and the Weak Equivalence Principle are foundational principles on which the standard description of the fundamental interactions is based. The validity of such basi…
ATHENA -- First Production of Cold Antihydrogen and Beyond
ATHENA Collaboration, A. Kellerbauer, M. Amoretti +33
Atomic systems of antiparticles are the laboratories of choice for tests of CPT symmetry with antimatter. The ATHENA experiment was the first to report the production of copious am…
