The antihydrogen programme of the ASACUSA collaboration at the antiproton decelerator of CERN focuses on Rabi-type measurements of the ground-state hyperfine splitting of antihydro…
Hyperfine spectroscopy of hydrogen and antihydrogen in ASACUSA
E. Widmann, C. Amsler, S. Arguedas Cuendis +31
The ASACUSA collaboration at the Antiproton Decelerator of CERN aims at a precise measurement of the antihydrogen ground-state hyperfine structure as a test of the fundamental CPT…
Velocity selected production of metastable positronium
C. Amsler, M. Antonello, A. Belov +52
Positronium in the metastable state exhibits a low electrical polarizability and a long lifetime (1140 ns) making it a promising candidate for interferometry experiments wit…
Detector setup of the VIP2 Underground Experiment at LNGS
J. Marton, A. Pichler, H. Shi +25
The VIP2 experiment tests the Pauli Exclusion Principle with high sensitivity, by searching for Pauli-forbidden atomic transitions from the 2p to the 1s shell in copper at about 8k…
Wide acceptance measurement of the K/K ratio from Ni+Ni collisions at 1.91A GeV
