用类矢量论扩展的最小超对称标准模型(MSSM)一直是人们讨论的焦点。如果我们将类矢量场理论推广到NMSSM中,并让类矢量态粒子与单态(S)耦合,我们就能通过Z(3)群的断裂找到一种自然地产生1TeV附近类矢量态粒子质量的方法。与MSSM+矢量型模型相比,扩展到NMSSM的矢量型模型包含更多的Yukawa耦合,并且可以帮助我们调整规范耦合的重整化群(RG)轨迹,以统一交点。它们还可以帮助压低5+(5)+BAR+10+(10)BAR模型的规范RG-β函数,以便规范耦合的RG轨迹在朗道极点之前统一。在这种情况下,我们还讨论了类矢量扇区对希格斯质量的贡献。
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.
