Gravitational Behaviour of Antihydrogen at Rest
One of the fundamental questions of today’s physics concerns the action of gravity upon antimatter. No experimental direct measurement has ever been successfully performed with antimatter particles. CERN has thus launched a research program with the Antiproton Decelerator (AD) allowing to prepare a measurement of the effect of gravity on antihydrogen atoms.
The primary aim of this experiment is to determine how antimatter reacts to gravity.
