我们建议SU(5)‘在隐区向规范介导超对称破缺的可能情形发展，以消除超对称味道问题，并在Z12−中构造了一个有三个族的例子。我们给出的例子在可见部分有Pati-Salam类型的粒子分类，并且在低能量下没有奇异现象。我们指出，在10个矢量型5‘和5’对SU(5)中，有6到7个非常轻的5‘和5’对是可以实现的，这导致了一种不稳定的超对称破缺真空的可能性。提出了采用三个二圆环不同的紧固半径来达到所需的耦合强度的可能性。
We suggest SU(5)′ in the hidden sector toward a possible gauge mediated supersymmetry breaking scenario for removing the SUSY flavor problem, with an example constructed in Z12−Iwith three families. The example we present has the Pati–Salam type classification of particles in the observable sector and has no exotics at low energy. We point out that six or seven very light pairs of 5′and 5¯′out of ten vectorlike 5′and 5¯′pairs of SU(5)′ is achievable, leading to a possibility of an unstable supersymmetry breaking vacuum. The possibility of different compactification radii of three two tori toward achieving the needed coupling strength is also suggested.
