英文摘要: The minimal supersymmetry standard model (MSSM) extended with vectorlike theories have long been discussed. If we extend the vectorlike MSSM theory into NMSSM and let the vectorlike particles couple with the singlet (S), we find out a natural way to generate the vectorlike particle masses near 1 TeV through the breaking of the Z(3) group. Compared with the MSSM + vectorlike models, vectorlike models extended into NMSSM contain more Yukawa couplings and can help us adjust the renormalization group (RG) trajectories of the gauge couplings in order to unify the intersections. They can also help press down the gauge RG-beta functions for a 5 + (5) over bar + 10 + (10) over bar model, in order for the RG trajectories of the gauge couplings to unify before the Landau pole. We also discuss the Higgs mass contributed from the vectorlike sectors in this case.
