The AEgIS experiment at CERN: Probing antimatter gravity

The AE$\overline{g}$IS experiment at CERN’s Antiproton Decelerator is set up to precisely measure the gravitational interaction between matter and antimatter. For this purpose, antihydrogen will be formed from cold antiprotons and positronium, the hydrogen-like bound state of an electron and a posit...

Descripción
Sumario:The AE$\overline{g}$IS experiment at CERN’s Antiproton Decelerator is set up to precisely measure the gravitational interaction between matter and antimatter. For this purpose, antihydrogen will be formed from cold antiprotons and positronium, the hydrogen-like bound state of an electron and a positron. Subsequently, the free-fall acceleration of a cold horizontal beam of antihydrogen will be measured by a deflectometer. The present status, recent experimental progress and the medium-term plan of the AE$\overline{g}$IS experiment are presented.
