The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

Two Canadian physicists are relishing the news that a pair of subatomic particles they predicted more than five years ago has turned up at the Large Hadron Collider (LHC), the world's premier particle ...

Two new subatomic particles whose existence was predicted by Canadian particle physicists have been detected at the world's largest particle collider. The discovery of the particles, known as Xi_b'- ...

The isotope lead-208 was predicted to be extremely stable and perfectly spherical because of the “magic” numbers of electrons and protons orbiting its nucleus. When researchers blasted lead-208 with ...

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

A group of teenaged students from Cambridge, Ont., is hunting for new subatomic particles at the home of the world's largest atom-smasher, the Large Hadron Collider. The six boys and seven girls of ...

Sensors buried deep in the Antarctic ice may help physicists figure out how gravity works in the quantum realm, the smallest scale of existence. A team of physicists says they’ve figured out how to ...
