杂化弦的近Kaehler降维

Nearly-Kaehler dimensional reduction of the heterotic string

Athanasios Chatzistavrakidis, George Zoupanos

摘要:

讨论了近Kaehler流形上N=1个超对称Yang-Mills与N=1个10维N=1个杂化超引力耦合的四维有效作用量.近Kaehler流形是一类具有SU(3)-结构的流形,在六维空间中,所有齐次近Kaehler流形都包含在相应的非对称陪集空间加上群流形的类中.因此,很自然地应用陪集空间降维方案,使用这些陪集空间作为内部流形,以确定四维理论。

英文摘要:

The effective action in four dimensions resulting from the ten-dimensional N=1 heterotic supergravity coupled to N=1 supersymmetric Yang-Mills upon dimensional reduction over nearly-Kaehler manifolds is discussed. Nearly-Kaehler manifolds are an interesting class of manifolds admitting an SU(3)-structure and in six dimensions all homogeneous nearly-Kaehler manifolds are included in the class of the corresponding non-symmetric coset spaces plus a group manifold. Therefore it is natural to apply the Coset Space Dimensional Reduction scheme using these coset spaces as internal manifolds in order to determine the four-dimensional theory.
