Shall we see antimatter light?


In 2002 the ATHENA experiment announced the first production of antihydrogen atoms at cryogenic temperature. The achievement of this goal is a first major step in the application of spectroscopy techniques to antimatter atoms.

In the future, antihydrogen light is expected to make it possible to carry out very accurate CPT tests as well as, for the first time ever, tests on the gravitational interaction between matter and antimatter.

Over the last twelve months significant results have been obtained has been made 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 seminar will focus on the main scientific goals in the study of cold antihydrogen, the results obtained so far and the medium-term plans for the first measurements on the interaction between antiatoms and photons.
