Abstract
Quantum chromodynamics (QCD), the electroweak theory and general relativity currently give an accurate description of all known phenomena in fundamental physics. No experimental facts are known that disagree with these theories. The Standard Model (SM) incorporates QCD and the electroweak theory. Its matter content consists of spin 1/2 quarks and leptons, and spin 1 gauge bosons. They are considered to be elementary, meaning that they have no constituents. There are six quark flavors (up, down, charm, strange, top and bottom) and in addition to its spin each of the quarks has a second degree of freedom, called color, which can have three different values. There are also six different leptons, e, {nu}{sub e}, {mu}, {nu}{sub {mu}}, {tau} and {nu}{sub {tau}}. Forces between fermions due to the electroweak interaction are mediated by exchanges of four gauge bosons ({gamma}, W{sup +}, W{sup -} and Z{sup 0}); and the forces due to the strong interaction, or QCD, are mediated by eight gauge bosons, the gluons. An in depth description of the SM can be found in [1], [2].
