The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

Scientists at CERN have observed an unexpected phenomenon within the world’s largest particle accelerator that suggests that the heaviest and shortest-lived particles in the universe may not be as ...

Restricting a strange class of particles known as anyons to one dimension could force them into adopting one of two new forms, models suggest, hinting at new fundamental interactions in particle ...

In the development of particle physics, researchers have introduced an innovative particle encoding mechanism that promises to improve how information in particle physics is digitally registered and ...

Trillions of times smaller than a grain of sand and smaller than an atomic proton or neutron, quarks are among the smallest particles in the universe. They are essentially building blocks for ...

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 ...

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 ...

As they probe deeper into the heart of the atom, discovering ever smaller and more mysterious particles and particles within particles, scientists have succeeded in bringing the once stable world of ...

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 ...

At CERN’s Large Hadron Collider on the edge of Geneva, scientists have reported a surprising twist in the behavior of matter. Collisions inside the 27‑kilometer ring have produced what researchers ...

Estimating things that exist is generally easy, but when it comes to estimating things that do not exist, it's more difficult. This is something physicists from Poland and the UK are well aware of. To ...
