A hydrogen beam to characterize the ASACUSA antihydrogen hyperfine spectrometer
C. Malbrunot, M. Diermaier, M. C. Simon +19
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…
Laser stimulated deexcitation of Rydberg antihydrogen atoms
Daniel Comparat, Chloé Malbrunot
Antihydrogen atoms are routinely formed at CERN in a broad range of Rydberg states. Ground-state anti-atoms, those useful for precision measurements, are eventually produced throug…
Improved Search for Heavy Neutrinos and a Test of Lepton Universality in the Decay $π^+ \rightarrow \mbox{e}^+ ν$
R. E. Mischke, A. Aguilar-Arevalo, M. Aoki +21
Two results from the PIENU Experiment are presented reporting a test of lepton universality in pion decay and improved limits on heavy neutrinos coupling to positrons. The status o…
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…
Monte-Carlo based performance assessment of ASACUSA's antihydrogen detector
Y. Nagata, N. Kuroda, B. Kolbinger +15
An antihydrogen detector consisting of a thin BGO disk and a surrounding plastic scintillator hodoscope has been developed. We have characterized the two-dimensional positions sens…
