Standard Model
The very current state of the classification of elementary particles is the Standard Model. It describes the strong, weak, and electromagnetic fundamental interactions, using mediating gauge bosons. The species of gauge bosons are the gluons, W−, W+ and Z bosons, and the photons. The model also contains 24 fundamental particles, (12 particles and their associated anti-particles), which are the constituents of matter. Finally, it predicts the existence of a type of boson known as the Higgs boson.

Famous quotes containing the words standard and/or model:
“Neither I nor anyone else knows what a standard is. We all recognize a dishonorable act, but have no idea what honor is.”
—Anton Pavlovich Chekhov (1860–1904)
“If the man who paints only the tree, or flower, or other surface he sees before him were an artist, the king of artists would be the photographer. It is for the artist to do something beyond this: in portrait painting to put on canvas something more than the face the model wears for that one day; to paint the man, in short, as well as his features.”
—James Mcneill Whistler (1834–1903)
