论文摘要
我们提供了O3/O7东方的广阔景观，该景观从著名的一组完整的Calabi-yau三倍（CICY）中降落在著名的相交。我们提供与现象学相关的拓扑数据的分布，例如Erientifold-Odd Hodge数字，D3 tAdpole和O3和O7平面的多重性。有些令人惊讶的是，几乎所有这些方向都具有对形奇异性，其变形分支被方向投射出来。但是，它们可以解决，因此大多数的方向值实际上是从更大且可能是新的CY三倍组中降低的，这些Cy三倍可以通过Conifold Transitions从CICYS到达。我们观察到一类有趣的类$ \ Mathcal {n} = 1 $涉及碰撞O-Planes的几何过渡。最后，作为一个应用程序，我们使用数据集生成了满足拓扑要求的方向示例，以实现\ cite {hebecker：2018yxs}中提出的超轻质喉咙轴（\ textit {thraxions}）的存在。可以在https://www.desy.de/~westphal/orientifold_webpage/cicy_orientifolds.html上访问数据库
We present a vast landscape of O3/O7 orientifolds that descends from the famous set of complete intersection Calabi-Yau threefolds (CICY). We give distributions of topological data relevant for phenomenology such as the orientifold-odd Hodge numbers, the D3-tadpole, and multiplicities of O3 and O7-planes. Somewhat surprisingly, almost all of these orientifolds have conifold singularities whose deformation branches are projected out by the orientifolding. However, they can be resolved, so most of the orientifolds actually descend from a much larger and possibly new set of CY threefolds that can be reached from the CICYs via conifold transitions. We observe an interesting class of $\mathcal{N}=1$ geometric transitions involving colliding O-planes. Finally, as an application, we use our dataset to produce examples of orientifolds that satisfy the topological requirements for the existence of ultra-light throat axions (\textit{thraxions}) as proposed in \cite{Hebecker:2018yxs}.
