Standard Model

The Standard Model of particle physics is a theory of three of the four known fundamental interactions and the elementary particles that take part in these interactions. These particles make up all visible matter in the universe.


Every high energy physics experiment carried out since the mid-20th century has eventually yielded findings consistent with the Standard Model. Still, the Standard Model falls short of being a complete theory of fundamental interactions because it does not include gravitation, dark matter, or dark energy.

It is not quite a copmlete description of leptons either, because it does not describe nonzero neutrino masses, although simple natural extensions do.


The standard model is a gauge theory of the strong (SU(3)) and electroweak (SU(2)×U(1)) and thus interaction with the gauge group (sometimes called the Standard Model symmetry group) is SU(3)×SU(2)×U(1). It does not take into account gravitation, which is SO(3,1).
