由冻结奇点构造新的超对称弦模空间

New Supersymmetric String Moduli Spaces from Frozen Singularities

Héctor Parra De Freitas

摘要:

目前八维和七维的$\mathcal{N} = 1$弦论的分类完全被具有F-理论或M-理论冻结奇点的K3曲面所捕获。在本注记中,我们证明了有不同的方法可以冻结具有相同ADE类型的某些奇点集合,因此在模空间中有比以前认为的更多的连通分量,即在8维中多一个,在7维中多三个。我们认为,八维空间中的新分量解压缩为九维空间中的弦论,它具有秩为1的规范群,这是迄今尚未确定的。构造和研究对应于这些模空间的弦描述是一篇配套论文的主题。

英文摘要:

The current classification of $\mathcal{N} = 1$ string theories in eight and seven dimensions is completely captured by K3 surfaces with F-Theory or M-Theory frozen singularities. In this note we show that there are inequivalent ways of freezing certain collections of singularities which have the same ADE type, and so there are more connected components in the moduli space than previously thought; namely, one more in eight dimensions and three more in seven dimensions. We argue that the new component in eight dimensions decompactifies to a string theory in nine dimensions with rank 1 gauge group, which has been so far unidentified. Constructing and studying the stringy descriptions corresponding to these moduli spaces is the subject of a companion paper.
