GENEVA (AP) — The physics lab that’s home to the world’s largest atom smasher announced on Tuesday the observation of three new “exotic particles” that could provide clues about the force that binds subatomic particles together.
The observation of a new type of pentaquark and the first duo of tetraquarks at CERN, the Geneva-area home to the Large Hadron Collider, offers a new angle to assess the “strong force” that holds together the nuclei of atoms.
