Glueballs are particles composed entirely of force-carrying gluons, predicted by the Standard Model but previously unobserved. Recent data from the BES III experiment provides strong evidence for their existence. If confirmed, this validates our foundational understanding of the strong nuclear force and how it binds matter together at the subatomic level.
Glueballs are particles made of pure force. New data from the BES III experiment suggests we have finally found evidence for these elusive components of matter.
