Description
I will discuss laser spectroscopy, particularly on the 1S-2S transition, of Hydrogen (H) and Antihydrogen (Hbar). The study of H recalls the work done at MIT in mid 90's and the setup under construction at UFRJ. The work with Hbar is done at the ALPHA collaboration at CERN. Details on line shapes, transition rates, detection schemes, will be discussed. The work has intimate connection to fundamental physics tests such as Charge-Parity-Time (CPT) symmetry, Quantum-Electrodynamics (QED), and Lattice-QCD tests as it is advancing towards predicting the proton charge radius.
