SU(3)结构几何上弦紧化的量子修正

Quantum Corrections in String Compactifications on SU(3) Structure Geometries

Mariana Grana, Jan Louis, Ulrich Theis, Daniel Waldram

摘要:

我们研究了SU(3)结构几何上紧化的II型弦论经典四维低能有效作用量的量子修正。在对低能自由度作一些简单的假设下,采用了以前为Calabi-Yau紧化所发展的各种方法来确定α '和弦耦合常数中模空间度规的主要微扰修正.我们发现-在完全类似的卡-丘的情况下-的修正采取一个普遍的形式,只依赖于欧拉特征的六维紧致空间。

英文摘要:

We investigate quantum corrections to the classical four-dimensional low-energy effective action of type II string theory compactified on SU(3) structure geometries. Various methods previously developed for Calabi-Yau compactifications are adopted to determine - under some simple assumptions about the low-energy degrees of freedom - the leading perturbative corrections to the moduli space metrics in both alpha' and the string coupling constant. We find - in complete analogy to the Calabi-Yau case - that the corrections take a universal form dependent only on the Euler characteristic of the six-dimensional compact space.
