Particle Physics Fundamentals
Unofficial explainers on the science associated with CERN's research (this is not CERN content).
The Standard Model
- Quarks — Six flavors of fundamental particles that combine to form protons and neutrons.
- Leptons — Fundamental particles including electrons and neutrinos that do not feel the strong force.
- Bosons — Force-carrying particles including photons, gluons, and the Higgs boson.
The Collider
- Large Hadron Collider — A 27-kilometer ring near Geneva that accelerates protons to near light speed.
- ATLAS and CMS — Two general-purpose detectors used to independently confirm particle discoveries.
- Collision Energy — How higher energy collisions let physicists probe smaller distance scales.
Landmark Discoveries
- Higgs Boson (2012) — The particle confirming the mechanism that gives other particles mass.
- Antiproton Discovery — Confirmed the existence of antimatter counterparts to ordinary protons.
- W and Z Bosons — Force carriers of the weak nuclear interaction, discovered in the 1980s.
