Antimatter-Matter Asymmetry

Authors: George Rajna

Researchers at the CERN particle-physics laboratory in Switzerland used laser spectroscopy to scrutinize the fine structure of antihydrogen, revealing with an uncertainty of a few percent that the tiny difference in energy of states — known as the Lamb shift — is the same as it is in normal hydrogen. [27] Researchers in Italy and Switzerland have performed the first ever double-slit-like experiment on antimatter using a Talbot-Lau interferometer and a positron beam. [26] Two new experiments at CERN, ALPHA-g and GBAR, have now started their journey towards answering this question. [25]
