Summary
Neutral antimatter atoms afford the unique opportunity to investigate the properties of antimatter with the latest atomic-physics techniques. In this way, different approaches to explaining the imbalance between matter and antimatter in the Universe may be tested. The AEGIS experiment located at the Antiproton Decelerator at CERN is dedicated to the question how antimatter behaves in the gravitational field of the earth. A deviation from normal gravitational acceleration would violate the weak equivalence principle of General Relativity.
