Description
A number of experiments at CERN’s Antiproton Decelerator aim to measure the properties of antihydrogen to find structural differences hinting at CPT symmetry breaking that would explain the observed baryon-antibaryon asymmetry in our universe. These experiments detect antihydrogen through annihilation making the antiproton-nucleus (
The Monte Carlo simulations of these events rely on physics models developed for high energies and theoretically extrapolated to lower energies. Previous measurements from the AD experiments, including the ASACUSA-Cusp collaboration show that the simulations do not reproduce the measured data. As even the annihilation mechanism itself is not well understood, a permanent beamline for slow extraction of sub-keV antiprotons is being set up at the ASACUSA facility, in order to measure the
