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 ...

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 ...

Data from the Large Hadron Collider (LHC) outside Geneva appears to have proved the existence of particles made of five quarks, solving a 50-year-old puzzle about the building blocks of matter, ...

Physicists working with the LHCb experiment at CERN have proven that a subatomic particle can switch into its antiparticle and back again. The researchers were able to prove this using extremely ...

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 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 ...

Of all the subatomic particles that have any mass at all, the neutrino is the lightest by far. In comparison, the electron, itself a quantum featherweight, has a mass that is at least 500,000 times ...

Quantum mechanics is simultaneously beautiful and frustrating. Its explanatory power is unmatched. Armed with the machinery of quantum theory, we have unlocked the secrets of atomic power, divined the ...

The energetic particles are currently bombarding satellites orbiting Earth, peppering their imaging systems and disrupting ...
