本文对有利完全交Calabi-Yau三重上正二项单子丛的所有杂种优势Calabi-Yau紧化进行了全面的分析。我们发现，原始数据集的约7000个模型包含91个标准的模型，我们详细描述。对这些模型的威尔逊线破缺的进一步分析表明，它们中没有一个能精确地产生标准模型的物质场内容。我们的结论是，完全相交的卡-丘流形上的正二项单子的整个集合被排除在唯象的理由。我们也采取了第一步，在分析较大的类的非积极单子。特别地，我们在这个类中构建了一个超对称杂种优势标准模型。这个模型具有标准模型规范群和额外的U（1）B− L对称性，恰好有三个夸克族和轻子族，一对希格斯二重态，没有反族或任何种类的奇异粒子。
A complete analysis of all heterotic Calabi-Yau compactifications based on positive two-term monad bundles over favourable complete intersection Calabi-Yau threefolds is performed. We show that the original data set of about 7000 models contains 91 standard-like models which we describe in detail. A closer analysis of Wilson-line breaking for these models reveals that none of them gives rise to precisely the matter field content of the standard model. We conclude that the entire set of positive two-term monads on complete intersection Calabi-Yau manifolds is ruled out on phenomenological grounds. We also take a first step in analyzing the larger class of non-positive monads. In particular, we construct a supersymmetric heterotic standard model within this class. This model has the standard model gauge group and an additional U (1) B− L symmetry, precisely three families of quarks and leptons, one pair of Higgs doublets and no anti-families or exotics of any kind.
