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…
Matching problem for primary and secondary signals in dual-phase TPC detectors
B. Radics, E. Burjons, A. Rubbia
The problem of matching primary and secondary light signals, belonging to the same event, is presented in the context of dual-phase time projection chambers. In large-scale detecto…
A 4 tonne demonstrator for large-scale dual-phase liquid argon time projection chambers
B. Aimard, Ch. Alt, J. Asaadi +169
A 10 kilo-tonne dual-phase liquid argon TPC is one of the detector options considered for the Deep Underground Neutrino Experiment (DUNE). The detector technology relies on amplifi…
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…
Search for a Hypothetical 16.7 MeV Gauge Boson and Dark Photons in the NA64 Experiment at CERN
D. Banerjee, V. E. Burtsev, A. G. Chumakov +45
We report the first results on a direct search for a new 16.7 MeV boson (X) which could explain the anomalous excess of e+e- pairs observed in the excited Be-8 nucleus decays. Due…
