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 ...

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 ...

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 ...

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 ...

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 LHCb collaboration is far less famous than CMS or ATLAS, but the particles and antiparticles they produce, containing charm and bottom quarks, holds new physics hints that the other detectors ...

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 ...

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 ...
