European researchers say they have discovered a new subatomic particle that helps confirm our knowledge about how quarks bind — one of the basic forces in the shaping of matter.
The CERN physics research center said Friday that the particle was predicted long ago, but finding it was “really kind of a classic tour de force of experimental work.”
Known as an excited neutral Xi-b baryon, the particle could not be detected directly because it was too unstable.
