Physics with Antihydrogen Atoms
Prof. Dr. Joel Fajans (University of California, Berkeley)

Since trapping antihydrogen atoms in 2010, the ALPHA collaboration has begun to test fundamental symmetries with antihydrogen atoms (a test of CPT), a direct limit on matter-antimatter gravity with freefall type measurements (a test of weak equivalence principle), and a 10ppb measurement of the charge of antihydrogen atoms (a test of CPT and quantum anomaly cancellation).
