Feynman rules and static quantities of the charged vector bosons in a left-right supersymmetric extension of the standard model.

摘要

The Standard Model is reviewed and its extension is proposed to incorporate left-right symmetry as well as supersymmetry. Model principles are developed to build a gauge theory with supersymmetry and the minimal supersymmetric extension of the Standard Model (MSSM) is briefly discussed. The left-right supersymmetric extension of the Standard Model is introduced and the symmetry-breaking pattern is described. The physical vector bosons, the charginos and neutralinos, and the Higgs particles are identified. The Lagrangian terms for the interactions of the vector bosons A, ZL, ZR, WL, W R amongst themselves as well as all corresponding Feynman rules are written down. The interaction Lagrangian terms with three fields are obtained at least one of which is the Photon A or a neutral vector boson ZL or ZR or a charged vector boson WL or WR. Feynamn rules are written down for interactions with three fields at least one of which is the Photon A, or a charged vector boson WL or W R. The Feynman rules are used in order to calculate the anomalous magnetic moments and quadrupole moments of the charged vector bosons WL or WR of the left-right supersymmetric extension of the Standard Model.
