Will Antihydrogen Light Shine?
Abstract
In 2002 the ATHENA experiment announced the first production of antihydrogen atoms at cryogenic temperature. This achievement is an important step towards antimatter atoms fine spectroscopy. Antihydrogen light is expected to make it possible to carry out very accurate CPT invariance measurements as well as, for the first time ever, tests on the gravitational interaction between matter and antimatter with important consequences for cosmology. Over the last two years significant results have been obtained in the investigation of antihydrogen production mechanisms. They are all the more important given the strong limitations imposed by the neutral atom trapping techniques required for fine spectroscopy measurements. This talk will focus on the main scientific motivations in the study of cold antihydrogen, the results obtained so far and the medium-term plans for the first measurements of the interaction between antiatoms and photons.
