Amid the chaotic chains of events that ensue when protons smash together at the Large Hadron Collider in Europe, one particle has popped up that appears to go to pieces in a peculiar way. All eyes are ...

Using the world's most powerful particle accelerator, the Large Hadron Collider, scientists have found that the quark-gluon ...

In its first moments, the infant universe was a trillion-degree-hot soup of quarks and gluons. These elementary particles ...

The CMS and ATLAS experiments at CERN’s Large Hadron Collider have observed an unforeseen feature in the behaviour of top quarks that suggests that these heaviest of all elementary particles form a ...

QGP is conventionally described using relativistic hydrodynamic models and studied experimentally through heavy-ion collisions. There has been a long-standing discrepancy between theory and experiment ...

The Large Hadron Collider (LHC) is also a big hadron discoverer. The atom smasher near Geneva, Switzerland, is most famous for demonstrating the existence of the Higgs boson in 2012, a discovery that ...

University of Chicago scientists have solved a 20-year-old puzzle in particle physics using data from an experiment conducted for an entirely different purpose. Physicists had long known that ...

Observational first: physicists have used the ATLAS experiment at CERN to observe the production of top-quark and photon pairs. (Courtesy: CERN) For the first time, particle physicists have observed ...

Quark nugget dark matter models propose that dark matter may consist of macroscopic objects formed from bound collections of quarks in a stable configuration. These models, which include variants such ...

July 21, 2003--At the Conference on the Intersections of Particle and Nuclear Physics held May 2003 in New York City, researcher Stepan Stepanyan from the DOE Office of Science's Thomas Jefferson ...

Objects are made of atoms, and atoms are likewise the sum of their parts—electrons, protons, and neutrons. Dive into one of those protons or neutrons, however, and things get weird. Three particles ...

Researchers from the University of Rochester have helped measure the elusive top quark with unparalleled precision, and the surprising results affect everything from the Higgs boson, nicknamed the ...
