Standard Model


Standard model is the ultimate model in universe in particle physics. it is used to explain the fundamental interaction in universe.

There exist four fundamental interaction in universe. These fundamental interaction is also called fundamental forces in universe. The fourse fundamental interaction in universe is strong force, weak force, electromagnetic force and gravitation. Standard model in particle physics can explain three fundamental interaction in universe from out of four fundamental interaction.Higgs Boson particle

The existence of quark is experimentally proved. The existences of quark is the evidence of authenticity of standard model. Tau nutrino, Top quark and  is the strength of standard model.

 The limitation of standard model is that it can not explain the gravitation in universe, baryonic asymmetry as well as nutrino oscillation. It contains no content of dark matter.
