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…
Antihydrogen level population evolution: impact of positron plasma length
B. Radics, Y. Yamazaki
Antihydrogen is produced by mixing an antiproton and a positron plasma in a cryogenic electromagnetic trap. The dominant antihydrogen formation mechanism is three-body recombinatio…
Scaling behaviour of the ground-state antihydrogen yield from CTMC simulation as a function of positron density and temperature
B. Radics, D. J. Murtagh, Y. Yamazaki +1
Antihydrogen production has reached such a level that precision spectroscopic measurements of its properties are within reach. In particular, the ground-state level population is o…
New bounds from positronium decays on massless mirror dark photons
C. Vigo, L. Gerchow, B. Radics +3
We present the results of a search for a hidden mirror sector in positronium decays with a sensitivity comparable with the bounds set by the prediction of the primordial He a…
Excitation of positronium from 2S to 20P state
M. W. Heiss, G. Wichmann, B. Radics +1
We report the observation of positronium excitation from the 2S to the 20P state. The Rydberg positronium atoms fly a distance of 40 mm before being field ionized and detected in a…
Estimation of antihydrogen properties in experiments with small signal deficit
Balint Radics
For a class of precision CPT-invariance test measurements using antihydrogen, a deficit in the data indicates the presence of the signal. The construction of classical confidence i…
A new approach for the ortho-positronium lifetime determination in a vacuum cavity
C. Vigo, M. Raajimakers, L. Gerchow +3
Currently, the experimental uncertainty for the determination of the ortho-positronium (o-Ps) decay rate is at 150 ppm precision; this is two orders of magnitude lower than the the…
