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 ...

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 ...

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 ...

What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into the ...

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of the ...

WASHINGTON, Aug 10 (Reuters) - The peculiar wobble of a subatomic particle called a muon in a U.S. laboratory experiment is making scientists increasingly suspect they are missing something in their ...

Physicists at CERN have reported the first observations of matter-antimatter imbalance in a subatomic particle 'baryon', offering clues as to why matter dominates in the universe. Particles of ...
