A pair of top quarks has been detected in the detritus spraying forth from the collision of two atoms of lead. It's the first time that this specific quark-antiquark pair has been spotted in a ...

Researchers at CERN’s Large Hadron Collider (LHC) have detected a phenomenon that happens only every trillion proton collisions, after observing the production of a single top quark along with a W and ...

According to theoretical predictions, within a millionth of a second after the Big Bang, nucleons had not yet formed, and matter existed as a hot, dense "soup" composed of freely moving quarks and ...

Neutron stars are so named because in the simplest of models they are made of neutrons. They form when the core of a large star collapses, and the weight of gravity causes atoms to collapse. Electrons ...

A pair of top quarks has been detected in the detritus spraying forth from the collision of two atoms of lead. This means that we're a step closer to taking new measurements of this primordial soup, ...
