本文研究了非超对称杂化SO(16)×SO(16)弦的轨道折叠和光滑的Calabi-Yau紧化。我们专注于这样的卡-丘背景,以回收常用的技术,如指数定理和上同调理论,以确定费米子和玻色子的4D光谱。我们认为,N=0理论从来没有导致快子光滑Calabi-Yaus在大体积近似。由于扭曲的快子可能出现在某些奇异的轨道上,我们推测这种快子状态在完全爆炸时被解除。我们对选定的orbifold几何形状进行模型搜索。特别是,我们构建了一个明确的例子,一个标准模型的理论与三代和一个单一的希格斯场。
A bstractWe investigate orbifold and smooth Calabi-Yau compactifications of the non-supersymmetric heterotic SO(16)×SO(16) string. We focus on such Calabi-Yau backgrounds in order to recycle commonly employed techniques, like index theorems and cohomology theory, to determine both the fermionic and bosonic 4D spectra. We argue that the N=0 theory never leads to tachyons on smooth Calabi-Yaus in the large volume approximation. As twisted tachyons may arise on certain singular orbifolds, we conjecture that such tachyonic states are lifted in the full blow-up. We perform model searches on selected orbifold geometries. In particular, we construct an explicit example of a Standard Model-like theory with three generations and a single Higgs field.
