Tests of the universality of the free-fall and non-relativistic QED with cold antiatoms

by Ruggero Caravita (Istituto Nazionale di Fisica Nucleare)

Europe/Rome
Description

Cold antimatter physics offers a prime and exotic testing ground for both the Universality of the Free-Fall i.e., the equivalence between inertial and gravitational masses (today accurately established for matter systems) and bound-state Quantum Electrodynamics, predicting the perfect equality between matter and antimatter atoms' transition frequencies as a consequence of the CPT symmetry. Positronium, the short-lived bound state of an electron and a positron, and antihydrogen, the stable bound state of a positron and an antiproton, are among the very few candidate systems allowing to probe these theoretical boundaries within the antimatter sector. The state-of-the-art in the laboratory research with pulsed antihydrogen and positronium beams towards the first generation of inertial-sensitive experiments, as well as the second generation of precision spectroscopy experiments with a particular focus to laser cooling of positronium, is presented.
