Physicists Detect Exotic Particles in Quark-Gluon Plasma physics science
Collaboration at CERN’s Large Hadron Collider have detected about 100 particles of a type known as X in quark-gluon plasma, an environment that they hope will illuminate the particles’ as-yet unknown structure.. found evidence of X particles in the quark-gluon plasma produced in CERN’s Large Hadron Collider.

“We suspect that X is either a compact tetraquark or an entirely new kind of molecule made from not atoms but two loosely bound mesons — subatomic particles that themselves are made from two quarks.”in 2003 by the Belle experiment, a particle collider in Japan that smashes together high-energy electrons and positrons.
“But people thought it would be too difficult to search for them because there are so many other particles produced in this quark soup.” “After the quark-gluon plasma forms and cools down, there are so many particles produced, the background is overwhelming,” Dr. Lee said.
