Christian Smorra (CERN)05/08/2015, 14:00Invited TalkCPT symmetry in the Standard Model reflects the equivalence of antiparticles and their matter conjugates in the fundamental interactions, excluding gravity. It predicts that such conjugate pairs have identical masses, lifetimes, charges and magnetic moments, the latter two of opposite sign. Single antiprotons confined and thermalized in a cryogenic Penning-trap system allow performing...Go to contribution page

Dr Laszlo Liszkay (IRFU CEA Saclay)05/08/2015, 14:30Invited TalkA key step of the GBAR experiment (Gravitational Behaviour of Antihydrogen at Rest) is the production of the positively charged antihydrogen ion. It can be cooled to cryogenic temperature and used for the creation of a cold neutral antihydrogen atom for the direct measurement of the effect of gravitation. The ion will be produced in two steps. The first is the charge exchange reaction between...Go to contribution page

Sebastian Wolf (Johannes Gutenberg-Univesity Mainz)05/08/2015, 15:00Invited TalkWe aim for free-fall experiments with antimatter atoms to determine its acceleration in the earth gravitational field. In such drop experiments and with drop heights below 1 m a temperature of a few µK is crucial to achieve the targeted accuracy of $\Delta g / g$ at the sub-percent level. The GBAR-collaboration will use positively charged anti-Hydrogen ions ($p^- + 2e^+$) formed at the ELENA...Go to contribution page
