Scientists at the Relativistic Heavy Ion Collider have observed particles emerging directly from empty ...

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), ...

An unforeseen feature in proton-proton collisions previously observed by the CMS experiment at CERN's Large Hadron Collider (LHC) has now been confirmed by its sister experiment ATLAS. High-energy ...

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 ...

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, ...

As if atoms weren’t already mind-blowingly small, never mind subatomic particles, CERN researchers in the CMS Collaboration were sifting through data from the Large Hadron Collider (LHC) and ...

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 ...

By tracing the origins of an unusual, short-lived particle, researchers have gathered some of the strongest evidence yet that ...

The Universe just after the Big Bang was similar to... a liquid. Physicists today are managing to recreate this state in the ...

Top result: An artist's impression of top-quark entanglement. The line between the particles emphasizes the non-separability of the top-quark pair, which is produced by LHC collisions and recorded by ...

All good things come in threes. The Standard Model of particle physics takes this motto to heart: it contains three so-called generations of elementary particles. Take the quarks as an example. In ...
