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 ...

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 ...

Event display of the excess of top-quark pairs. Credit: CMS collaboration/CERN The CMS collaboration at CERN has observed an unexpected feature in data produced by the Large Hadron Collider (LHC), ...

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 ...

CERN’s Large Hadron Collider (LHC) is designed to probe the fringes of known physics, and now the facility has found particles not behaving as predicted. While it’s still early days, the discovery ...

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 ...

Trillions of times smaller than a grain of sand and smaller than an atomic proton or neutron, quarks are among the smallest particles in the universe. They are essentially building blocks for ...

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 ...
