Astrophysicists are closing in on one of the strangest possibilities in stellar evolution, a compact remnant that might sit ...

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 ...

Fleeting connection Artist’s impression of toponium, which is a top quark and antitop quark that are briefly bound by an exchange of gluons. (Courtesy: D Dominguez/CERN) For decades, physicists ...

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.

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 ...

Heavy-ion physics is a dynamic field that investigates the behaviour of matter under extreme conditions by colliding nuclei at relativistic speeds. Such collisions create a short-lived, ...

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 ...

BUFFALO, N.Y. — Scientists have observed the Higgs boson interacting with the top quark, the heaviest known elementary particle, in an exciting discovery that deepens our understanding of why objects ...

Protons may be intrinsically charming. The subatomic particles are a mash-up of three lighter particles called quarks: two of the type known as up quarks and one down quark. But physicists have ...

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 ...
