Abstract

Almost ten years after the first production of cold antimatter at CERN, the confinement of antihydrogen has recently been achieved for the first time. Several experiments installed at the Antiproton Decelerator intend to test the symmetry between matter and antimatter by means of trapped anti-atoms. In addition, in the coming years it is planned to study the effect of gravity on antiparticles for the first time. Meanwhile, evidence from the Large Hadron Collider hinting at a violation of charge–parity symmetry beyond the Standard Model of particle physics has yet to be confirmed. A violation of the discrete symmetries that describe the relation between matter and antimatter could explain the excess of ordinary matter in the Universe.
