There is very little antimatter on Earth. From cosmological observations, we also know that there is more matter than antimatter in the Universe. However, the baryogenesis mechanisms derived from the Standard Model of particle physics predict that there should be much more antimatter than what is observed.
Where is all the missing antimatter gone?
At CERN, the cold antihydrogen program pushes the frontiers of our understanding of the Universe. I will introduce the baryonic asymmetry riddle and give a status on the antihydrogen program at AEgIS.
