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 ...

Inside the Large Hadron Collider, protons slam together at nearly the speed of light, creating a brief fireball of quarks and ...

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 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 ...

In their search for more flavors of Higgs bosons, a team of researchers at CERN stumbled across what could be evidence of the smallest matter-antimatter particle ever. The hypoethical particle, known ...

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 ...

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 ...

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 ...

This spring, at a meeting of Syracuse University’s quark physics group, Ivan Polyakov announced that he had uncovered the fingerprints of a semi-mythical particle. “We said, ‘This is impossible. What ...
