我们构造了T6/2 × 2上的IIA型定向折叠,它允许不可因子分解格.我们描述了一种处理这种构型的方法,并讨论了紧化格对蝌蚪相消条件的影响。此外,我们包括不平行于O 6-平面的D 6-膜。这些膜可以在四维空间中产生手征谱,从而揭示了相交D膜模型构造中的一个新角落。我们证明了一个明确的例子的建设。一般来说,我们认为,获得奇数的家庭是有问题的。
We construct type IIA orientifolds on T6/2 × 2 which admit non factorisable lattices. We describe a method to deal with this kind of configurations and discuss how the compactification lattice affects the tadpole cancellation conditions. Moreover, we include D6-branes which are not parallel to O6-planes. These branes can give rise to chiral spectra in four dimensions, thus uncovering a new corner in the landscape of intersecting D-brane model constructions. We demonstrate the construction at an explicit example. In general we argue that obtaining an odd number of families is problematic.
