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), ...

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, ...

NEWPORT NEWS, VA – Inside the nucleus of the atom, the building blocks of matter are anything but static. Individual particles are in a constant state of energetic motion, like dancers on a dance ...

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 ...

Scientists studying particle collisions at CERN have captured new evidence of how quarks move through the early universe’s primordial plasma.

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 ...

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 ...

A large and unexpected excess of top quark pairs has the physics community excited, but the interpretation is still up for debate. In 1995, Alexander Grohsjean cut out a story from the local German ...

Protons are particles that exist in the nucleus of all atoms, with their number defining the elements themselves. Protons, however, are not fundamental particles. Rather, they are composite particles ...
