2nd International Workshop on Antimatter and Gravity ( WAG 2013 )

13 Nov 2013, 08:00 → 15 Nov 2013, 14:30 Europe/Zurich

The purpose of this meeting is to review the experimental and theoretical aspects of the interaction of antimatter with gravity. Tests of the weak equivalence principle with e.g. positronium, muonium and antihydrogen will be discussed. Progress reports on the experiments at the CERN Antiproton Decelerator and on the available future facilities will be presented. A session on the relevance of antimatter with respect to Dark Energy and Dark Matter in the Universe (theory and experiments) is also foreseen.

See www.einstein.unibe.ch/workshops/wag2013.html for further information (e.g. if you wish to contribute to the workshop) or contact marcella.esposito@lhep.unibe.ch .
