Mais qu’est ce que c’est ?Tetraquark : des scientifiques détectent une particule qui pourrait être une nouvelle forme de matière (et si vous êtes gentils, ils vous diront même à quoi ça sert)
Le Z(4430) est une particule composée de quatre quarks. Le CERN a récemment confirmé son observation, et donc l'existence de hadrons exotiques en état de tetraquark, un état qui ne saurait être classé selon le modèle habituel des quarks.
