Welcome to the ASACUSA homepageASACUSA is an antimatter experiment at CERN's
Antiproton Decelerator (AD) studying:
Antiprotonic helium atoms with laser spectroscopy to test the symmetry between matter and antimatter (CPT) by a precise determination of the antiproton-to-electron mass ratio.
The antihydrogen ground-state hyperfine structure to test CPT.
Atomic and nuclear collision cross sections of antiprotons at low (<100 keV) energies.
