Particle physics applications of the AWAKE acceleration scheme
A. Caldwell, J. Chappell, P. Crivelli +11
The AWAKE experiment had a very successful Run 1 (2016-8), demonstrating proton-driven plasma wakefield acceleration for the first time, through the observation of the modulation o…
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…
The positronium hyperfine structure: Progress towards a direct measurement of the transition in vacuum
M. Heiss, G. Wichmann, A. Rubbia +1
We present the current status for the direct measurement of the positronium hyperfine structure using the $\text{2}^\text{3}\text{S}_\text{1} \rightarrow \text{2}^\text{1}\text{S}_…
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…
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…
