IIB型通量紧致化的质谱--关于AdS真空和共形维数的评论

Mass spectrum of type IIB flux compactifications -- comments on AdS vacua and conformal dimensions

Erik Plauschinn

摘要:

本文研究了IIB型通量紧致化的质谱。我们首先给出了四维N=1超引力理论中F项真空的质量矩阵的一般性讨论,然后专门讨论了存在几何和非几何通量的IIB型Calabi-Yau定向折叠紧化。F-项真空在这种设置是在一般的AdS $_4$真空,我们计算的共形维数的运营商对偶的标量场。对于DGKT构造的镜像对偶,我们发现对复结构模空间的单圈修正导致实值共形维数-只有当忽略这些修正时,我们才恢复了文献中先前报道的整数值。对于一个比DGKT镜更一般的通量配置的例子,我们也得到了非整数共形维数。此外,我们认为,稳定的模空间的渐近区域中的模意味着至少有一个质量本征值发散。

英文摘要:

In this note we study the mass spectrum of type IIB flux compactifications. We first give a general discussion of the mass matrix for F-term vacua in four-dimensional N=1 supergravity theories and then specialize to type IIB Calabi-Yau orientifold compactifications in the presence of geometric and non-geometric fluxes. F-term vacua in this setting are in general AdS$_4$ vacua for which we compute the conformal dimensions of operators dual to the scalar fields. For the mirror-dual of the DGKT construction we find that one-loop corrections to the complex-structure moduli space lead to real-valued conformal dimensions - only when ignoring these corrections we recover the integer values previously reported in the literature. For an example of a flux configurations more general than the DGKT mirror we also obtain non-integer conformal dimensions. Furthermore, we argue that stabilizing moduli in asymptotic regions of moduli space implies that at least one of the mass eigenvalue diverges.
