The most widely accepted theory of particle physics. It is the only one covered in this site.
The theoretical description of the forces of nature and elementary particles. It describes the fundamental forces between matter particles via the exchanges of bosons. Tested to high accuracy by experiments at the LEP accelerator at CERN, and elsewhere.
The modern theory of the interaction of elementary particles, comprising the Weinberg-Salam theory and quantum chromodynamics. It incorporates the concepts of quarks (6), leptons (6), their antimatter constiuents, forces and the force carriers.
The organization and relationships between fundamental particles. Click here for more information.
An ad hoc but amazingly successfull collection of theories that describes the four fundamental forces at energies currently accessible to experiments. The theories are the SU(2) x U(1) electroweak theory, the SU(3) (QCD) theory of strong interactions and the classical theory of general relativity for gravitation. The various particles and interactions are summarized in this diagram from the Particle Data Group. Visit CPEP's The Particle Adventure for more information.
Physicists' name for the theory of fundamental particles and their interactions. It is widely tested and is accepted as correct by particle physicists.
The very successful theory of quarks and leptons and their interactions.
Gauge theory encompassing the electroweak and strong interactions.
Electroweak theory, quantum chromodynamics and gauge theory form what particle physicists call the “standard model.
Physicists have developed a theory of fundamental particles and interactions called the Standard Model. This site describes various aspects of this model. [ ] [ Close Glossary
This is a detailed description of the standard model (SM) of particle physics. It describes how the leptons, quarks, gauge bosons and the Higgs particle fit together. It gives an outline of the main physics that the theory describes, and new directions in which it is moving.
