23. Towards antihydrogen 1s-2s Spectroscopy

The Charge-Parity-Time (CPT) symmetry predicts a perfect matching between an atom's and the antiatom's quantum structure. Following the production and trapping of antihydrogen $(\rm\overline H)$ atoms in experiments at CERN's Antiproton Decelerator (AD), it is now possible to attempt a high-precision comparison of the spectra of H and $\rm\overline H$. There are interests in the hyperfine...

On behalf of the ASACUSA-CUSP Collaboration The ASACUSA-CUSP collaboration at the CERN antiproton Decelerator (AD) aims at probing CPT symmetry through the precise comparison of hyperfine transitions in hydrogen and its CPT-conjugate: antihydrogen. The ground state hyperfine transition in hydrogen has been measured more than half a century ago in a beam with a relative precision of 4 ×...
