The idea that protons and neutrons were composed of even smaller particles, with non-integral electric charges, was proposed in 1963/64 by Andre Petermann, George Zweig and Murray Gell-Mann, who ...

Michael Riordan surveys the extraordinary year of 1964, which saw the birth of the quark model, the invention of the Higgs ...

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 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 ...

The top quark’s extreme mass makes it decay almost immediately after it is produced. “The top and antitop quarks just have ...

Researchers at the CERN Large Hadron Collider have discovered a doubly charming new particle, which has long been theorized to exist. Named Ξ cc ++ (Xi cc ++) (and no, we don't know how to pronounce ...

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 ...

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 ...
