Standard Model

The Standard Model is a collection of theories that describe fundamental particles of nature and the way in which they interact. It has been very successful in describing all of the nuclear and particle physics data that has been collected over the past 50 years. Despite this success, there is general suspicion among the physics community that the Standard Model may be only a low-energy approximation to a more illuminating theory--one that would include a description of gravity, predict elementary particle masses and reveal the origin of discrete symmetry breaking, such as parity violation. See the Standard Model for more information.
