The Standard Model of particle physics is described by its symmetries — or the symmetry group (SU(2)xU(1)) under which matter contents transform. So the introduction of this symmetry is very important. In fact, virtually all particle physicists believe that standard model is only an effective theory of some more fundamental theory. The discrepancy can be greatly reduced by introducing supersummetry (See Fig. The result will help experimentalists to scrutinize the Standard Model of particle physics at accelerators such as CERN's Large Hadron Collider and Fermilab's Tevatron. The Standard Model has been fantastically successful, in that it is capable of predicting how particles will behave to very high accuracy. 2008, Nambu receives half of the Nobel Prize for introducing the concept of spontaneous symmetry breaking into particle physics, which led, for example, to the explanation of why some particles have mass and others have not (Higgs mechanism). To start, we were introduced to the Standard Model of physics, a theory which identifies the set of forces (except gravity) and particles which are believed to make up the whole of the universe (with some yet to be discovered). €�The current theoretical framework that describes elementary particles and their forces, known as the Standard Model, is based on experiments that started in 1897 with the discovery of the electron. The standard model is the name given in the 1970s to a theory of fundamental particles and how they interact.
