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 ...

Pentaquarks do not fit into the traditional quark model of hadrons, but understanding these exotic new particles is offering fresh insights into the subtleties of the strong interaction Five quarks In ...

The world's largest atom smasher has revealed a new kind of particle, and so far, it leads a charmed existence. The discovery of the particle, which is made up of two so-called charm quarks, validates ...

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 ...

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 ...

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 ...

Einstein proposed his special theory of relativity 120 years ago, and despite numerous attempts to challenge it, the theory still remains intact and valid. It is a simple but powerful concept that ...

The LHCb experiment at CERN's Large Hadron Collider has reported the observation of Xicc++ -- a new particle containing two charm quarks and one up quark. The existence of this particle from the ...

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 ...

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 ...

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 ...
