弦校正时空与SU(N)-结构流形

String Corrected Spacetimes and SU(N)-Structure Manifolds

Katrin Becker, Melanie Becker, Daniel Robbins

摘要:

利用有效场论方法和SU(N)-结构语言,研究了弦或M-理论到Minkowski空间的紧化对超对称约束的高阶导数修正.我们的分析完全是在目标空间中进行的,因此是非常一般的,并且不依赖于依赖于理论的细节,例如世界面超对称性的数量。对于实维数n<4的流形,我们证明了内部几何仍然是平坦的和未修正的。当n=4,6时,具有SU(N)-完整性的Kahler流形可以被修正为SU(N)-结构,同时保持超对称性。

英文摘要:

Using an effective field theory approach and the language of SU(N)-structures, we study higher derivative corrections to the supersymmetry constraints for compactifications of string or M-theory to Minkowski space. Our analysis is done entirely in the target space and is thus very general, and does not rely on theory-dependent details such as the amount of worldsheet supersymmetry. For manifolds of real dimension n<4 we show that the internal geometry remains flat and uncorrected. For n=4, 6, Kahler manifolds with SU(N)-holonomy can become corrected to SU(N)-structure, while preserving supersymmetry, once corrections are included.
