The AEgIS experiment carried out at CERN aims to form a cold antihydrogen beam to perform precision studies on gravity. A key ingredient is the creation of antihydrogen via a charge-exchange process between trapped antiprotons and Rydberg excited positronium atoms (Ps). In the present, the latest results of laser excitation of Ps are reviewed, as well as studies on a possible laser manipulation and cooling of Ps and antiprotons.

Abstract
The AEgIS experiment carried out at CERN aims to form a cold antihydrogen beam to perform precision studies on gravity. A key ingredient is the creation of antihydrogen via a charge-exchange process between trapped antiprotons and Rydberg excited positronium atoms (Ps). In the present, the latest results of laser excitation of Ps are reviewed, as well as studies on a possible laser manipulation and cooling of Ps and antiprotons.| File | Dimensione | Formato | |
