The Large Hadron Collider has given scientists their best look yet at the primordial matter that filled the universe moments ...

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

The CMS collaboration at CERN has observed an unexpected feature in data produced by the Large Hadron Collider (LHC), which could point to the existence of the smallest composite particle yet observed ...

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 ...

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 Collaboration investigated in detail events in which a top quark and an anti‑top quark are produced together in high‑energy proton–proton collisions at √s = 13 TeV, using the full 138 fb⁻¹ ...

After years of failed searches, CERN has finally caught a needle in a subatomic haystack: a heavy relative of the proton called Ξcc⁺. Ξ (or Xi) is a Greek letter pronounced like the word “Zye” (rhymes ...

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 ...

Probing ever deeper into the inner world of the atom, nuclear physicists have uncovered an increasingly baffling collection of tiny particles. Besides the familiar neutrons, electrons and protons, ...

Scientists have for the first time observed quantum entanglement — a state in which particles intermingle, losing their individuality so they can no longer be described separately — between quarks.
