我们提出了一种新的方法来打破大统一规范对称性通过细谷机制的模型，可以容纳手征费米子。伴随标量场是通过杂化弦理论中常用的对角嵌入方法实现的。作为例子，我们计算了在S^1/Z_2轨道上紧化的五维模型中伴随标量场的单圈有效势。结果表明，该势基本上与S^1模型中的势相同，因此，除了手征费米子外，文献中的结果也很容易实现。
We propose a novel way to break grand unified gauge symmetries via the Hosotani mechanism in models that can accommodate chiral fermions. Adjoint scalar fields are realized through the so-called diagonal embedding method which is often used in the heterotic string theory. We calculate the one-loop effective potential of the adjoint scalar field in a five dimensional model compactified on an S^1/Z_2 orbifold, as an illustration. It turns out that the potential is basically the same as the one in an S^1 model, and thus the results in literatures, in addition to the chiral fermions, can be realized easily.
