环面上的不可因式分解膜

Non-Factorizable Branes on the Torus

Harun Omer

摘要:

本文从矩阵分解的角度讨论了具有任意Z_4 × Z_4或Z_2 × Z_2轨道作用的环面上的弦紧化。该方法已达到可以在这些背景上构建模型的水平。虽然在文献中讨论的膜通常包裹可因子化的圈,即是1-圈的乘积的圈,但这里研究的膜可以在一般的同调类中,可以具有任意位置和威尔逊线,具有完全的复结构,分别具有Kahler模依赖性,并且可以服从任何一致的orientifold作用。它显示了任何所需的D-膜可以系统地构造。三点积分器可以用一个例子来计算。没有讨论它们的正常化。

英文摘要:

This work discusses string compactifications on the torus with optional Z_4 x Z_4 or Z_2 x Z_2 orbifold action from the perspective of matrix factorizations. The method is brought to a level where model building on these backgrounds is possible. Whereas branes discussed in the literature typically wrap factorizable cycles, that is cycles which are products of 1-cycles, branes studied here can be in generic homology classes, can have arbitrary position and Wilson line, have full complex structure respectively Kahler moduli dependence and can be subject to any consistent orientifold action. It is shown how any desired D-brane can be constructed systematically. Three-point correlators can be computed as is demonstrated at hand of an example. Their normalization is not discussed.
