From The Big Think, July 16, 2022: Fermilab’s Don Lincoln writes about the evolution of new exotic forms of matter known as tetraquarks and pentaquarks. By studying these particles, it can help scientists understand the strong nuclear force inside atoms and provide insights into the early Universe.
The newly discovered tetraquark provides a unique window into the interactions of the particles that make up atoms.
For the first time, the LHCb collaboration at CERN has observed an exotic particle made up of four charm quarks.
Researchers found four new particles made of the same four building blocks.
From ars technica, Feb. 29, 2016: Fermilab’s found a brand-new species—the first particle with four flavors of quarks.
From IFL Science, Feb. 27, 2016: Scientists on the DZero experiment have found an incredible new particle that’s part of the exotic family of tetraquarks.
From Scientific American, Feb. 26, 2016: Evidence for a never-before-seen particle containing four types of quark has shown up in data from the Tevatron collider at Fermilab.
From Gizmodo, Feb. 25, 2016: Physicists from the DZero collaboration have announced the discovery of a new particle, believed to be part of an exotic family called “tetraquarks.”
DZero announces the newest member of the tetraquark family.
