✦ Synopsis
The precision spectroscopy of antiprotonic helium has steadily advanced in recent years, yielding a CPT test of the difference of antiproton and proton charge and mass of < 10 ppb. Experiments with a new laser system currently under way promise to improve the accuracy by a factor 5-10. An experiment being developed to measure the hyperfine splitting of antihydrogen is described. * on behalf of the ASACUSA collaboration Nuclear Physics A 752 (2005) 87c-96c
