摘要: Within the framework of supersymmetry, the particle content is extended in a way that eachHiggs doublet is in a full generation. Namely in addition to ordinary three generations, there is an extra vector-like generation, and it is the extra slepton SU(2)L doublets that are taken to be the two Higgs doublets. R-parity violating interactions contain ordinary Yukawa interactions.Breaking of supersymmetry and gauge symmetry are analyzed. Fermion and boson spectra arecalculated. Phenomenological constraints and relevant new physics at Large Hadron Collider arediscussed.
