Overview of recent work on laser excitation of positronium for the formation of antihydrogen

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 re...

Descripción
Sumario: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.
