Particle Physics And Representation Theory
The connection between particle physics and representation theory is a natural connection, first noted in the 1930s by Eugene Wigner, between the properties of elementary particles and the structure of Lie groups and Lie algebras. According to this connection, the different quantum states of an elementary particle give rise to an irreducible representation of the Poincaré group. Moreover, the properties of the various particles, including their spectra, can be related to representations of Lie algebras, corresponding to "approximate symmetries" of the universe.
