论文摘要
大统一组（肠道）是通过$ \ z_ {12-i} $ orbifold cartactification从SO（32）异源字符串构建的。到目前为止，大多数来自弦乐紧凑型的现象学研究都依赖于$ \ ee8 $杂丝，这引起了SO（32）杂种弦，对将来的现象学研究非常有用。在这里，通过对SU（$ n $）的反对称张量表示来实现自发对称性破裂。本文中提出的反su（$ n $）与SO的旋转表示（$ 2N $）的翻转SU（$ n $）完全不同。在这里，我们意识到手性表示：$ \ tsix \ oplus 5 \ cdot \ nineb $用于su（9）肠道和$ 3 \ {{\ ten}'_ l \ oplus {\ fix fix fix fift}'_ l \ \}'_ l \ \} $ for su（su（5）$'$'$ ut。特别是，我们确认SU（9）量规组的非亚洲异常消失，因此我们的紧凑型方案达到了关键要求。我们还介绍了Yukawa联轴器，特别是最重的费米昂，$ t $和最轻的费米子，中微子。在超对称版本中，我们提出了一个方案，如何通过限制量规组SU（9）动态地打破超对称性。可见行业中的三个家庭被解释为SU（5）$'$ ut的手性光谱。
Grand unification groups (GUTs) are constructed from SO(32) heterotic string via $\Z_{12-I}$ orbifold compactification. So far, most phenomenological studies from string compactification relied on $\EE8$ heterotic string, and this invites the SO(32) heterotic string very useful for future phenomenological studies. Here, spontaneous symmetry breaking is achieved by Higgsing of the anti-symmetric tensor representations of SU($N$). The anti-SU($N$) presented in this paper is a completely different class from the flipped-SU($N$)s from the spinor representations of SO($2N$). Here, we realize chiral representations: $\tsix\oplus 5\cdot\nineb $ for a SU(9) GUT and $3\{{\ten}'_L\oplus {\fiveb}'_L\}$ for a SU(5)$'$ GUT. In particular, we confirm that the non-Abelian anomalies of SU(9) gauge group vanish and hence our compactification scheme achieves the key requirement. We also present the Yukawa couplings, in particular for the heaviest fermion, $t$, and lightest fermions, neutrinos. In the supersymmetric version, we present a scenario how supersymmetry can be broken dynamically via the confining gauge group SU(9). Three families in the visible sector are interpreted as the chiral spectra of SU(5)$'$ GUT.
