The Antiproton Decelerator (AD) facility at CERN [European Organization for Nuclear Research] ... is a unique source of antimatter. It delivers antiprotons with very low kinetic energies, enabling physicists to study the fundamental properties of baryonic antimatter – namely antiprotons, antiprotonic helium and antihydrogen – with great precision. 1, record 1, English, - baryonic%20antimatter

Mais lorsque la matière et l'antimatière entrent en contact, elles s'annihilent et disparaissent dans une bouffée d'énergie. Or le Big Bang devrait avoir créé matière et antimatière en quantités égales. Alors, pourquoi y a-t-il bien plus de matière que d'antimatière dans l'Univers? 3, record 2, French, - antimati%C3%A8re
