R Symmetry And R Symmetry Anomaly

The main content of this thesis is the gauge symmetry in Standard model and the R symme-try in the Supersymmetry model.The first part of this thesis will introduce the gauge symmetry in the Standard model.The Standard model has made great achievement in particle physics reach,it can describe the strong and weak interaction by the gauge theory successfully.And the gauge symmetry anomaly in the Standard model is also introduced.then the second part is talking about the supersymmetry which is an important subject of beyond Standard model research,and the min-mal supersymmetry Standard model is discussed in this part.Finally,thesis will present that the R symmetry makes great contributions in supersymmetry model building.what is more,discrete R symmetry anomaly cancellation,non-anomalous discrete R symmetry and the gauge R symmetry in E6 great unification theory is the last part of this thesis.
