An unforeseen feature in proton-proton collisions previously observed by the CMS experiment at CERN's Large Hadron Collider ...

Scientists at CERN have observed an unexpected phenomenon within the world’s largest particle accelerator that suggests that ...

Exotic four-quark particle spotted at Large Hadron Collider Rare tetraquark is one of dozens of non-elementary particles discovered by the accelerator, and could help to test theories about strong ...

Researchers discovered that sometimes, before the Lambda-b fragments into these byproducts, it transforms into a new particle consisting of five quarks: two up quarks, a down quark, a charm quark and ...

Nature - Collision debris yields five-quark particle. Nakano himself might never have thought to look for the five-quark particle had it not been for a series of lunchtime conversations with ...

Both teams were looking at a particle called Y(4260) that had been discovered in 2005 but whose nature has mystified researchers since. By smashing together electrons and their antiparticle ...

In a never-before-seen particle, four quarks of a feather flock together. Physicists think they have detected the first conglomerate of four quarks incorporating more than two of the same kind.

Although the quark–gluon plasma at the LHC vanishes after about 10-23 s, scientists can study it by analysing how other particles produced in collisions move through it. The top quark is the heaviest ...

In a first-of-its-kind experiment conducted at the world's most powerful particle accelerator, the Large Hadron Collider (LHC), scientists have attempted to discover if the universe's heaviest ...

Several recent findings have suggested particles with greater quark numbers (SN: 12/13/03, p. 381: Available to subscribers at Hints emerge of a four-quark particle), but other data haven’t ...
