Top quark data may encode quantum magic, but the closer scientists look, the more selection, modeling, and proof matter every ...

CERN’s Large Hadron Collider (LHC) is designed to probe the fringes of known physics, and now the facility has found particles not behaving as predicted. While it’s still early days, the discovery ...

At CERN’s Large Hadron Collider on the edge of Geneva, scientists have reported a surprising twist in the behavior of matter.

Scientists working at CERN's Large Hadron Collider Beauty (LHCb) experiment announced that they have finally figured out the structure of an exotic particle known as the pentaquark, meaning a group of ...

A new theory suggests the universe’s greatest secrets are hiding in a “zeptouniverse” that’s ready to be explored—without ...

The ALICE experiment of the Large Hadron Collider has, for the first time, directly measured a phenomenon known as the "deadcone," which has allowed physicists to directly measure the mass of a ...

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 ...

X marks the spot: the CMS experiment at CERN undergoing an upgrade. (Courtesy: Maximilien Brice/CERN) A mysterious “X” particle comprising four quarks and first seen in 2003, has been found in the ...

No pairs: the first ‘open flavour’ tetraquark has been spotted at CERN (Courtesy: Shutterstock/paul_june) The first tetraquark composed of four quarks of ...
