论文摘要
杂种线捆绑模型构建的系统程序为粒子物理学提供了大量的标准模型（SLM）。在本文中，我们继续在全面的完整交叉点Calabi Yau（Gcicy）歧管的情况下继续这项工作。使用参考文献中构建的gcicys。 [1]，我们确定了两个几何形状，这些几何形状与线束总和结合在一起，直接适用于异肠模型。然后，我们证明这些gcicys承认自由地表现$ \ mathbb {z} _2 $对称组，因此可以适合Wilson line line Breaking the Gut Gauge组的标准模型。我们对这些几何形状进行了系统扫描，分别导致99和33 slms。对于第一类模型，可以将我们的结果与同等等效的完整相交Calabi Yau歧管上的线束模型进行比较。这表明现实配置的数量是相同的数量级。
The systematic program of heterotic line bundle model building has resulted in a wealth of standard-like models (SLM) for particle physics. In this paper, we continue this work in the setting of generalised Complete Intersection Calabi Yau (gCICY) manifolds. Using the gCICYs constructed in Ref. [1], we identify two geometries that, when combined with line bundle sums, are directly suitable for heterotic GUT models. We then show that these gCICYs admit freely acting $\mathbb{Z}_2$ symmetry groups, and are thus amenable to Wilson line breaking of the GUT gauge group to that of the standard model. We proceed to a systematic scan over line bundle sums over these geometries, that result in 99 and 33 SLMs, respectively. For the first class of models, our results may be compared to line bundle models on homotopically equivalent Complete Intersection Calabi Yau manifolds. This shows that the number of realistic configurations is of the same order of magnitude.
