结果表明，如果矢量超场的动能项非最小，则 N=1 超引力理论的 GUT 尺度可以与普朗克尺度一样大。遵循 sin2θW(MW)、α3(MW) 和 mbmτ(MW) 的规范值。在这些理论中，SU(3)、SU(2) 和 U(1) 高吉诺的质量在统一尺度上可能不同。在极端情况下讨论了低能粒子谱的后果，其中一个高吉诺质量很大而另外两个质量消失。
It is shown that N=1 supergravity theories can have a GUT scale as large as the Planck scale if the kinetic energy terms for vector superfields are non-minimal. The canonical values for sin2θW(MW), α3(MW) and mbmτ(MW) are respected. In those theories masses of SU(3), SU(2) and U(1) gauginos may be different at the unification scale. Consequences for the low-energy particle spectrum are discussed in the extreme case where one of the gaugino masses is large while the other two vanish.
